The communication with the host was fine - we didn't meet Antoine (only met his nice flatmate Adrien), but we knew we could reach him whenever we needed. Fortunatelly we didn't have to, cause he left us everything he said he will and more. The apartment is very nice. There is a gorgeous view of London. It's well equipped with appliances. It's not exactly close to the bus/tube, but we already knew that. The neighbourhood seemed safe, although we saw a fox one night :). The building is very safe. There are 3 or 4 supermakets on the way from the tube. I would stay there again and of course recommend it to a friend as a lovely stay in London.
