Unfortunately, this was my only bad experience in my years on Airbnb and a guest and a superhost. In short, Austria announced a lockdown the day of my trip so I communicated with Gunter and he kindly agreed to cancel my reservation and thus I decided not to do the trip. The next day Gunter sent me a message that he won't cancel the reservation after all because he wanted to get compensated, at which point he stopped responding. I, of course was forced to cancel the reservation, being charged one extra night due to the delay. When I politely asked Gunter if he could at least issue a partial refund for the extra night I had to pay him, again with no reply. Airbnb helpdesk also contacted him but with no results. The feeling of unfairness and of being misled is definitely way more unpleasant than the financial loss of this whole story.
