With Airbnb generally, it's expected for the host to reply to a message after a booking is confirmed (eg to communicate arrival time and other organizational matters etc). With this host, no-one replied to messages. It may cause worry to other travelers booking through Airbnb. The apartment was grand, clean and in a great location. There was a problem with one of the shower trays and a lot of water used to leak out onto the floor. Thus we were confined to the one shower in the other bathroom.
