Carol's place is really nice located in the center of London. We didn't have any problem with the location. The room is clean but really cold (maybe a heating will be appropriate for that room). The room is also a bit noisy. The main problem of the appartement is that is not clean in the common rooms : the kitchen was a big mess (we decided to clean it ourself to cook something) and the toilet are also very dirty. Carol wasn't here during our stay, so I may be thinking that the roommate is very missy. She's also not very polite (didn't greet us in the morning and close up the door of the kitchen while we wanted to take our breakfast). The friend of Carol, Petra is a very nice person, and she explain everything about the appartement in a really nice way.
