John is adorable and reactive. We had an issue with the heating system and he was prompt to come and solve it the most satisfying way. The flat is very well located, close to public transportation and major points of interest in London. It’s a quiet place with a nice view to a green garden at the back. The double beds at the first level are very comfortable, neither too soft or too firm. Arrival and departure are easy and practical, no risk to stay outside without finding the exact place and the keys. Thank you John.
