Message from my friends, for who I booked this room as I couldn't host them myself (well, I live in Coventry and they wanted to stay in London): "Really friendly and available host. The flat is around 3 minutes to the underground and less than a minute to a bus stop. Some proximity shops are accross the street. Restaurants are only a few minutes by foot . There is no traffic noise even if the window’s bedroom is located on the street side."
I'll add they gladly recommend Malte as a host.
