The flat is exactly what is described. It is perfectly located on a quiet street in an excellent area, only 2 mins from covent garden underground. We stayed for 5 nights last week. The two bedrooms and 1.5 baths worked well for me, my wife and 2 teenage sons. My wife esp. loved the kitchen, which is well equipped, although we only used it for breakfast. The dryer didn't work but not a big problem as Ann has an airing rack for us to hang the clothes dry.
Ann was flexible and nice enough to arrange for meeting us early in the AM on the first day despite that the rooms needed to be cleaned. We stored the luggage in the hall, went thru the checkin process, got our keys and went out for our tour for the rest of the day.
We would love to have this place again if we come back to London next time. Highly recommended for family of 3-4 ppl.
