We stayed at David's small flat for 6 nights in London. It is indeed small, but with the use of a murphy bed, the space is quite adequate. It is a nice bright quiet flat, facing south away from Sloane. On the 6th floor you are able to see nicely over the other buildings for a great view to Chelsea.
The S.Kensington tube is just an easy few blocks away. There is a Saintsbury store, restaurants, and even a Starbucks just blocks away. Great neighborhood.
The flat had an ample kitchen and nice bathroom with a great shower! There is also quite a bit of storage space in the closets to put things - which we really appreciated.
We enjoyed coming back to this flat in the evening after a long day touring London, sitting down at the bay window and looking out at the sunset!
We would definitely return and thought this place was great value for the money.
