I loved staying at Sophie's. She is fantastic person who was very helpful with advice on the local and wider area (places to eat, how to get around and the like). Her home is lovely and she is a wonderful host.
I really enjoyed the area where Sophie lives. I walk around cities when I can so being in London and near The Regent's Park, Camden and even being able to take a walk up to Hampstead Heath was great. However, if you're not a lover of walking there are a couple tube stations, an overground and numerous bus stops near by (I, also, used each of these while I stayed).
There is good food in the area, in a number of directions within walking distance and if you like pubs there are different styles around as well.
I'm sold on the area and the place to rest my head!
