First, Nina is a stellar host. She went beyond our expectations by being thoughtful and generous in many ways. Second, the flat is so sweet, simple, and perfect for a couple. You can spend hours in Kensington Gardens like we did, or you can jump on any of the three (or more?) nearby tube stations to get anywhere. We appreciated that the flat was very quiet for a city flat. If we return to London, we will certainly stay here again.
