Yan is a very friendly, helpful and accommodating host. She provided all the info we needed before we arrived, answering any questions I had promptly, and made us feel very welcome when got there.
The apartment is in a quiet residential area and perfect for our needs: quiet, comfy and close to public transport for accessing central London and Heathrow.
I will certainly recommend Yan's place to friends looking for a similar size place to stay when visiting London.
