If you are thinking about to rent this room, I really do recommend. It was exactly what I wanted. Not only the bedroom is cosy, but the house at all, a typical british flat, very well located, in a good and calm neighborhood. There is a bus stop a few steps of the house that can take you to the start point underground station to explore the city within 10-15 minutes. There is also a supermarket quite closer to the house where you can buy stuff for cooking and eating. The kitchen is large and well equipped, the bathroom is quite clean and the living room is really relaxing.
Felipe is a very welcoming host, always happy and willing to help and a really good person to drink a beer together, he really made me feel at home.
If I were going back to London, I wouldn't think twice in choose Felipe's house again.
