If you're looking for something personal and lovely, this is NOT your place. You probably won't meet your hosts and the messages you get are all copy-paste and pre-written. This makes everything to do with organisation (check-in, etc.) very easy but I guess I just expected something a little different when I looked at the pictures.
Everything is in a very small space and there are other rooms with other guests. When everybody is "home", it's very cramped. Even for London, the price is extreme for what you get.
