The hosts got their friend to check us in as they were away. We had no communication with the friend and the host had very slow replies.
Their friend couldn't speak English very well so we couldn't ask them much questions and when I messaged the host i wouldn't get responses.
Wi-Fi didn't work for basically our whole stay as the password was incorrect and was fixed on our last day in Vienna which made our trio difficult as our phones didn't work there so we could not search or book anything.
