I am so lucky to be hosted by Mary and her husband. They are super nice and sweet people. We had good communications and they respect my privacy as well.
Also, their place is great: the location is so convenient - just 7mins walk to the central line station. Thus, you can get to the center very easy while enjoy a quiet environment.
Additionally, the room is clean and cozy, I felt relaxed and be just at home.
If I come back to London in the future, I will definitely stay with these two sweetest hosts again!
