We had a very good experience dealing with Properties Actually. When we first approached them for a suitable flat, they found some good options for us within our budget and managed to arrange a price which was fair for both the landlord and us. Further, they managed the repairs and maintenance for our flat and were extremely responsive whenever there was a problem. At times we needed some urgent matters to be taken care of like our main door lock broke down or a leak in the kitchen, they promptly attended to it. At times we felt the landlord was trying to delay fixing of the problem but Properties Actually would then intervene to resolve it.
During time of renewal of contract, they ensured the rent remained fair and in line with the market and hence we continued in the property for 4 years.
Overall we would have no hesitation in recommending them.
