Anna is a great host. Her apartment excedes our expectation: It's light, clean and spacious. We are in a group of 3, but I believe it can receive 4 person comfortably without using the living room to sleep.
The neighborhood is very good with supermarkets, restaurants and subway station very close to the flat.
Taking the tube leaving from the apartment we visited most of the London attractions with trips with no more than 30 minutes.
Anna is all the time taking care that everything works well on the flat, and is very responsive. It was a great stay. We've been there for 9 nights with nothing to complain.
