My stay at Nana's couldn't have been lovelier. She made sure she was there to check me in and show me around even after my flight was delayed, was helpful and communicative whenever I had questions, and was extremely accommodating. The space is perfect for a short or long time stay and is in a cute and safe neighborhood (there's even a park within walking distance). It's a bit far from central London, but it's also a nice break from the city bustle. Very much recommend, especially for solo travelers!
