Lovely accommodation and host, and the location is GREAT: it's a five-minute walk from Acton Town tube station. There is a Sainsbury's Local (and two other convenience stores that stay open late) right by the tube station. It's very convenient for getting to/from Heathrow via Tube (about 20 minutes), and it's about the same into Central London.
The room is large and bright, very private, with a very comfortable bed and well appointed en suite.
Communication with Ruth was great, and she was very helpful.
Highly recommended.
