Mary is the best host. There was a plane problem and a baggage problem, but she kept caring until it was solved. It was easy to understand because she explained how to enter the accommodation in person when I checked in. She also provided additional necessary items for free, and the response was very fast. The heating was very good and I was able to spend five days in London comfortably. If I have to visit London again next time, I really want to stay there again. I strongly recommend this accommodation!
