A Truly Outstanding Experience with Wessam Working with Wessam has been an absolute pleasure from beginning to end. Throughout the process, Wessam was reliable, well-informed, and incredibly helpful. Whether it was arranging viewings, answering questions, or keeping me updated. I would wholeheartedly recommend Wessam. He's a credit to his profession, and I’m very grateful for all his help.

I was very impressed with O'Sullivan super professional services and tremendous help throughout the process of finding a suitable tenancy for me. Gleb was excellent to deal with. Very easy to get on with and always on hand to answer any questions. He was professional at all times and wasn't "smarmy and slippery" like some other estate agents. He is 100% genuine and I can recommend his services highly enough.

Amazing service and experience. A wind of fresh air in the polluted and unprofessional world of real estates. Trust, service and attention to details. I could spend a big paragraph detailing how Hamza and his team supported my purchasing process, I will mention only one point: how the CEO of this company personally delivered the keys of my new home to my address, accompanied with a bottle of champagne. Look no further: you are in good hands! Gio

Hamza Lakhany and his team of professional subject matter experts, have been providing me advice for properties in London since 2012. Over this period I can highly recommend their expertise, professional, unbiased and trustworthy advice. O’Sullivan is very agile, responsive and responsible. You will get a real time reading of the property market and can expect a solid suggestion on best options for your personal circumstances.

Katerina and Zahira at O’Sullivan Property Consultants are exceptional! I highly recommend them, they should be the go-to agents for both landlords and tenants. Their professionalism, knowledge, and attention to detail are second to none. Any landlord would be in safe hands with their management expertise. They make the whole process smooth and stress-free, and it’s clear they genuinely care about delivering the best service.

Couldn’t be more happier. ‘Ahmad’ specifically and the whole team @ O’Sullivan were very professional, responsive and efficient. We were dealing with another property consultant for the same property and chose not to continue with them, we chose O’Sullivan as we really liked Ahmad and his team. Highly recommended. Many thanks.PositiveResponsiveness, Professionalism

I cannot say how terrible this team is. O'Sullivans let us an apartment that they are "managing" on behalf of the landlord. We rented a one bed in a relatively new build in central London and have had the worst experience we've ever had. …

Excellent experience! O'Sullivan is head and shoulders above other agencies I worked with. Very smart, sensible, and entirely devout of cheap sales gimmicks - which was greatly appreciated. Highly recommend!

I've had an excellent experience with O'Sullivan Properties. They were professional and very helpful. I was looking for an apartment in a particular very demanded building and they found it for me. I needed to move in in two days, therefore they did everything fast and efficient, so I moved in on time. They do deserve the best boutique agent award as they are the best. I highly recommend their services.
