My wife and I had a great time in London, not only because London is a fantastic city but also because we had a great place to stay.
Stephan's house is a beautiful and comfortable place where you will find everything you need. We didn't spend too much time in the area but what we saw and visited was realy nice (the Cafe 7, the Forest Tavern and the Co-Op), everything only a few minutes by foot from the house. Also the buses and trains are very nearby, so you can reach the city fast and without any zrouble.
Stephen was a great host, our communication was always as helpful as uncomplicated.
