The host was very helpful as we were in a bit of a jam for a place to stay. He got back to us in one hour.
As for location, it could not be better. Walking to the underground (central line) station is only a few minutes. Hyde park is about five minutes away on foot. We found that the Victoria and Albert museum a pleasant walk.
The flat/apartment was large and comfortable with a full kitchen, a master suite, and a second bedroom. There is a cot available in the living room, which we used. I would highly recommend the
location.
