John was an absolutely fantastic host, and his flat was wonderful - everything I was hoping it would be. The flat is located within walking distance to two (and soon, three!) underground stations, and there is a great grocery store just down the block from the flat. The flat also has a dishwasher and (wonderfully) heated tile floors in the kitchen and bathroom - so great for those chilly London days and nights. As far as the pictures go, what you see is what you get - clean, modern - the pictures are completely accurate.
John was truly a gem of a host - happy (and quick) to help whenever I had a question of any kind, including fantastic travel advice for London, France, and Ireland. I couldn't have asked for a more pleasant experience.
