I booked the flat for my parents who came to visit me in December, and they simply loved the flat. The building is quite new, with concierge and welcoming entrance. The flat is easy to reach with lift, and very cozy. It's perfect for a couple or single and has everything you need in terms of utensil in the kitchen, and good quality ones!! We managed to have dinner in twice and found everything we needed, the we chilled on the nice sofa and armchair watching TV! The bed is king size and very comfy, lots of pillows and nice soft bedsheets. The bathroom is good sized (considering London standard) with both bath tub and shower.
The location is very good, next to a Sainsbury local and the high street with shops and bars. Transports are quite close as well, just few minutes walks away.
I will definitely consider it for them for next time they come, and I strongly recommend it to anyone looking for an accommodation in London.
