I booked a room at Anne Abel Smith's home for my mother who came in London for holydays and she was more than satisfied.
She told me the room was clean, tidy and comfortable. Anne Abel Smith is very accomodating and pleasant. Dogs are very discreet and very nice! The neighborhood is quiet, close to bus back to central London, and there's a very nice park close to home.
Address to recommend and that makes you want to return!
