The regulations by general terms and conditions for the hotel industry 2006 re valid.
In the event of a border or hotel closure or a lockdown, you can cancel free of charge, even at short notice.

For this we recommend the hotel cancellation insurance of the Europäische Reiseversicherung. http://start.europaeische.at/hsp?AGN=508858
