I had a very bad experience with this host: at our arrive noone was there and we have to wait one hour to receive password to come in the house. After that, we found the apartment dirty and mess: the housecleneer wasn't been there before our arrive.
The host did not respond to our messages before the late evening, when he sent an apology message. The Airbnb support was valuable and very professional. We have had to find another solution for our travel in London.
