Flat is great but "host" (actually an employee of the company that manages this and many other flats) does not check or respond to messages via Airbnb or on his telephone number.
As a result, we ended up waiting half an hour at the flat for him to let us in.
He asked us to call before we arrived, we texted many times --- no response and he didn't show up until 10 minutes after we finally decided to call.
