Atousa and Rezza are wonderful hosts, wonderful people. Kind, helpful, flexible, extremely intelligent professionals. The room is spacious, clean, and has an excellent modern bathroom, and you can use their very nice washer-dryer for laundry. The building is modern and very well constructed, with an elevator. My stay was nearly four weeks long, and I was very comfortable. For research at the National Archives the location is perfect, just a little over 300 yards to the entrance. A Marks & Spencer department store with a small but excellent grocery is just 500 yards away (note that guests can use the kitchen). It's just 1/2 mile to Kew Gardens station on the District line, and the excellent restaurants nearby; the Kew Gardens entrance is just a quarter mile more. High-end shopping and many more restaurants are one stop down the line in Richmond proper. Or you can walk just 200 yards and board the R68 bus to Richmond.
As I have more research to do, I'll be staying here again next year.
