I would definitely recommand Rosemary's house if you wish to visit London. The house is located in the quiet neighbor, and also there's a small park nearby!
Rosemary was very welcoming, kind, and intelligent lady, and I enjoyed chatting with her.
The room is just like the photo. You can use desk, drawer, and closet. Also there's some tea, coffee and water in the room.
I'd like to revisit Rosemary if i'll come back to London.
