As an independent London estate agency with a reputation for outstanding customer service, much of our business is generated through client recommendations. Our small team will support you throughout, bringing an intimate knowledge and understanding of your needs.
For us, success is connecting the right home to the right buyer at the right price. For sales it means creating bespoke marketing plans to optimize the visibility of your property, with enhanced techniques that go beyond traditional methods.

Why We Love What We Do
“
"To anyone embarking on their London journey or contemplating a real estate venture, we echo with heartfelt conviction: Everybody needs an Ugo in their life. She is not just a realtor; she is a luminary whose brilliance lights the path to unforgettable experiences and cherished memories.
Ugo, you are truly special, and we are immensely grateful to have crossed paths with you."

"Ugo is the best in the business! My husband and I had no idea how to go about buying a property in London, which is very different than purchasing in America. Ugo walked us through the ins and outs. She took her time to explain how everything works. She also listened intently to our needs and expectations. Due to her care for us as clients and wanting the best for us, she found us the perfect home within two days!
With her knowledge of the market, she knew we could purchase the flat below the asking price and worked hard to get us a great deal.
I would never use anyone else when buying property in the U.K. She truly takes care of her clients.
Ugo is kind, intelligent, honest and supportive!"

"It was a pleasure working with Ugo. Ugo was a true gem. As an American and a first time buyer in the UK, Ugo was indispensable in all aspects of the purchase. It is far to say I couldn’t and wouldn’t have done it without her. Although I had always wanted to purchase a property in the UK, I was always intimidated. Ugo made it happen!"

"Exceptionally high quality service is what can be expected from Ugo Arinzeh and her professional Onyx Property team at Keller Williams. We discovered Ugo through her fantastic and informational YouTube videos and were immediately drawn to her. Even though we have been visiting England for over 30 years, we quickly realized, as overseas buyers, the real estate purchasing process was very different from what we experienced in Manhattan and Bermuda where we also have homes.
Early on we recognized Ugo's expertise and understanding for both the American and UK markets and this made her the ideal choice as our real estate agent. Our ten day London visit to search for a two bedroom flat went seamlessly thanks to the efforts of the Onyx Property team. Our several site visits were efficiently organized and reflected our amenity preferences. We appreciated viewing flats in different boroughs to get a sense of which neighborhoods appealed to us the most.
A definite advantage to working with the Onyx Property team is their willingness to share high calibre referrals for services we required such as a solicitor, insurance agent, etc. They also scheduled flat/building surveys which were extremely important and comprehensive. We could never have done all of this so quickly or efficiently. Throughout this entire real estate process communication with the team has been responsive and positive.
Pleased and grateful sums up how we feel about our experience with working with Ugo and her Onyx Property team."

"Moving house is stressful, and having Ugo and her lovely assistant help me put my flat to rent took a lot of stress off. Her attention to detail, kindness and all-round helpfulness made the process easeful. I was very happy with the selection process and diverse choice of really great tenants. Her team maximised marketing, making our on-line presentation beautiful - I'm just glad the tenants were as impressed with the real thing. Thanks Onyx!"

"As a young professional from the US and a first time home buyer, I needed help navigating the complex real estate processes in London where there was no go to agent to help you with your search. Ugo was the answer and provided an amazing full service showing me multiple properties, aggregating all the data on them, and ultimately guiding me to make the best decision on location / value. Her help was invaluable throughout the buyer journey, from the first steps of finding a place to negotiating on price to locking in a mortgage to closing. She made it stress free for me and helped with all the complexities that came up as a first time buyer. If I had to do it all over again, I’d do it with Ugo."

"Ugo and her team were fantastic! I'm Canadian, and so was surprised to find out that buying agents are not as common in the UK. As a couple looking for their first family home together in London, we wanted someone to simplify the process for us. I found Ugo from her YouTube videos, and immediately knew we would gel.
Ugo was professional from the very beginning: she was with us for every single viewing, set up a group chat for us to discuss properties, and gave quality feedback to narrow down our wish list. Her team arranged every viewing in advance, which saved us so much time and stress, and grouped them together in times that worked for our busy work schedules.
Having Ugo look after our interests was invaluable as we took the plunge. Thank you, Ugo!"

"We wanted to write a quick review about our positive experience getting our flat rented out quickly. Ugo and team did an amazing job taking photographs of the flat and surrounding neighborhood and putting together an attractive promotional flier. We received eight offers and with guidance from the Onyx team we picked the tenants. The last hurdle was getting all of the paperwork in order and helping with utilities which we could not have done without help from Ugo and team. We are now happy landlords of our London flat!"

“Having decided to buy a flat in London I wasn’t relishing the task of endless searching to find exactly the right property for me. Luckily I was introduced to Ugo and the first thing she did was to help me define exactly what it was I was looking for.
Ugo has a fantastic knowledge of the London residential property market and she was able to give me an analysis of different areas with their pros and cons and different price points. In the end she suggested a location I hadn’t even thought of and eventually we found the perfect pied-à-terre at the right price.
Working with Ugo was a joy. She quietly takes away the stress of dealing with agents and sifting through listings. She was able to help with negotiating which allowed me to make the most efficient use of my time. Highly recommended!”

“From our initial email contact from our home in Canada to Ugo in London, it took less than a month to find the perfect apartment. Working with Ugo was a pleasure: she was very organized and efficient. Once we arrived in London, Ugo quickly determined what we were looking for and only showed us properties in our preferred district. Once we decided upon a property and everything was signed and finalized, she followed up to make sure stipulations in the contract were carried out. We would have no hesitation in recommending her.”

“As international clients, Onyx’s services were a perfect fit. They handled everything for us without us having to set foot in the U.K. Despite many complications on the other side, Onyx was able to achieve completion within just 4 weeks of listing and 2 prospective buyers with serious offers. We were able to sell our flat quickly and fulfil all of our obligations thanks to you and your team.”

“We worked with Ugo to help us renovate our flat in Chelsea that she had helped us buy. She and her team were extremely efficient in managing the entire process. We were presented options throughout and even with multiple unforeseen problems cropping up, we always felt that she knew what she was doing and a solution would be found. We are very happy with the outcome of the improvements and now have a beautiful home to enjoy for many years to come.”

“Onyx has managed our flat in Maida Vale for several years and we’ve been very pleased with the high level of service and attention we have received. Recently we approached the firm to assist with the refurbishment of another flat in St. Johns Wood. Ugo and her team completed the assignment in 2 weeks in line with budget. Both the high level of finish and quality of workmanship ensure we would highly recommend Onyx for these services.”

“My mom and I were referred to Ugo through a real estate agent in Turkey. We started our conversations through face-time and explained to her what we needed. Ugo made sure we had lots of options across each part of the city before we decided on a short-list. Throughout this process she never let us feel like we were running out of choices, she was very calming, also very honest and open about where we had to make and not make compromises. She was also very good at negotiating on behalf of us and we got ourselves a great place to live in London! Thank you for everything Ugo!”

“We could never have imagined that buying a home in London could have been an absolutely pain free process. From the first meeting to discuss our plans with Ugo we were completely at ease. She is so knowledgable, organised and impeccably professional. We had our hearts set on a property and her sharp instincts and negotiating skills made the difference in getting our offer accepted. From acceptance to exchange, her recommendations and guidance made the entire process seamless and incredibly quick. We first laid eyes on our family home in May and were unpacking dishes and bedsheets in August! This was the most important purchase of our lives and we could not have done it without her.”

“Not only did I achieve the asking price within one day; the sale itself, completed in record time of 4 weeks; I also saved myself the costs of travelling to the UK to oversee things. It has been an enjoyable experience. I very much doubt if any other agent could have achieved what Ugo did for my sale, and the outcome speaks for itself.”

"Ugo is just what I need - highly professional. I appreciate her honest opinion on what suits me as an international buyer investing in London. I like to look for my own properties, but Ugo is instrumental in getting the purchase agreed for me at the right price, beating off other offers. From agreeing the purchase to completion and then lettings, it was all hassle-free. I am now buying my second flat in London in one year - again through Ugo. Can't recommend her more, if you are looking for professionalism in an agent/consultant who gives you her dedicated service and takes pride in it."
