Me and my mother really enjoyed our stay at César and James' place. It was extremely clean and comfortable, and we slept really well. They were kind enough to leave out some extra amenities such as bread, juice and coffee, which we were so glad to be able to eat in the morning before we left.
The apartment is right opposite Putney Heath and a short walk from Richmond Park, where we were able to start out our day with a lovely walk. The bus goes from right outside which is also very convenient. We would definitely stay again, it's a great base to explore London from! I would definitely recommend it.
