First of all, Martin is a fantastic host! He was out of town when my girlfriend and I visited, but he gave us incredible instructions and arranged for us to pick up the keys from his cleaning lady. He was extremely easy to communicate with and answered emails all day long within minutes. The apartment is located in a great area, super close to Oxford Street, Covent Garden and so on. Although the underground is near by, you can pretty much walk everywhere. He arranged for us to checkout at noon which was really helpful too. The apartment is as described by Martin and I would definitely like to recommend him as a host!
