I had the best time with Cecilia and her family. They have the cutest airbnb, an amazing family (and cat), and in a great area in London.
Barnes is a great place to stay. It’s very bful, has it’s own pond, some wonderful cafes and great people. It’s also close enough to central London for you to just hop on a bus, cycle or take an uber. I was able to cycle my way to central for all four days.
Highly highly recommend!
