I would definitely recommend this place to everybody.

The flat was very clean, spacious and warm (our visit was in November).
Furthermore the kitchen was well equipped and there was a great access system so you don't have to be afraid to loose your keys.
The location couldn't be better: close to our office, close to shops and restaurants and very centered.
Some improvements could be: Street noise from nearby construction at times and the blinds are too thin in the bedrooms so lots of light comes in.
However, in general it was an excellent stay and we will definitely re-book if we need to go back to London for business purposes.
Thank you for hosting us!
