The location is absolutely perfect (you're a minute or two's walk from the tube, and about the same distance from restaurants and bars) , Roger is a gracious and laid back host (for us he baked some fresh bread that was terrific, and always had bananas and cereal at the ready early in the morning), and the room we had was spacious and comfortable.
Roger was a great conversationalist when appropriate, but also left us to our own devices, which was awesome.
We had a great time in London, and I don't think it would have been as magical as it was, had we not stumbled upon the perfect AirBnB.
