My sister and I had a great week at Cliff's. The location is really good: you can walk to the next underground station (colliers wood) in about 15 min. or even take a bus. So it's really easy to get to central London. The room was very cozy and after long days of walking in London we were happy to return to our room with the comfortable bed.
The bathroom is shared with Cliff and his famiy so be aware that it's about 5 people sharing one bathroom.
You have the great opportunity to use the kitchen but you have to pass through the living room to reach it.
All in all Cliff and his family were very nice hosts and we can recommend staying there.
