Pretty much everything you could ask for: location, cleanliness, friendliness. If you are working at the National Archives, you can't beat it: 5-minute walk away, next door to the M&S, and 6-8 minutes to Kew Station for an easy ride into the city on the District Line (and easy transfers to Piccadilly and other lines). The flat is quiet (if you don't mind the planes--all of Kew is on the LHR flightpath on some mornings) and spotless (which I especially appreciate). You are right next to the Thames--the path is perfect for long walks or runs. Very nice family. Everything I was hoping it might be for my first Airbnb rental.
