We stayed in Mary's apartment for 10 days, and we enjoyed it very very much.
The apartment was very clean and equipped with anything you need for such a long period of time.
The apartment is located in a very pleasant and nice neighborhood from which you can reach many other places by foot, underground or bus.
Mary is a very pleasant host. She helped us before arrival to London, and was very kind to let us enter the apartment early in the morning on the day of our arrival.
We recommend Mary's apartment very much!
