We have spent 4 nights in David and Savie's house in London. They have been the best hosts ever, helping us greatly when we encountered some problems. They are extremely friendly and welcoming, and we had very interesting conversations with David. The house is very clean and the room is comfortable. It is nice to be able to use the kitchen. We didn't know the neighbourhood but we really liked it : quiet (which is nice after a tiring day in London) but close to a lot of shops and restaurants. And you can go pretty much everywhere with buses or metros. I would definitely stay there again if I come back !
