Mary & Gigi have a very well located appt in zone 2. When we arrived we were a bit surprised that the room was part of their own appt but we had our own bathroom and the room and bed are really fine so there was nothing to complain about. But it is good to know you share the same front door and the same table where they have breakfast themselves. Both are very hospitable people so you feel welcome about anything you ask. I would definitely recommend staying at their appt while you are in Londen. It is a good place to stay for a very good price!
