I spent 3 nights at Oliver's house and would do it again. The room is on the 1st floor and reachable via staircase. The room and the bathroom are clean and the bed is comfortable. The area is quite and in front of the house there is a bus station and a small supermarket. You can reach London center within 30 min with public transportation. Close by are different restaurants and Chelsea is reachable within 15-30 min walk. I enjoyed talking with Oliver during breakfast and received some great recommendations from him.
