We were fully satisfied with Mary Ann's flat. The flat was cosy and quiet, equipped with everything you need. The location is good, you can find a tube and a coach station within a 3 minutes walk. There is a Tesco nearby and some restaurants. The local are seemed safe.
Although we didn't meet in person, Mary Ann was a great host, she was responsive and she provided us with useful information.
I absolutely recommend Mary Ann's apartment.
