The room is nice and clean, and the bed is really comfortable and there are hangers and shelves to put your clothes. They are very nice people, kind and helpful and the dogs are just adorable and friendly! The area is nice and safe and the tube station (which takes you easily to central London in about 30 minutes) is just a few minutes walking. There is also a bus stop just at the end of the street where you can take a bus that gets in 15 minutes to Clapham Junction (which is a main station where you can get to many other areas including central London and Gatwick Airport).
The only thing that I didn't like that much was that It was no possible to fully close the bedroom's door, but appart from that everything was good. I would recomend to stay at Amanda's house =)
