Hotel Schlussel closed without notifying us of cancellation. We had reservations for the last week of May. I always confirm reservation two weeks in advance. While this was an unpleasant surprise, I was able to secure new lodging today, but at a higher cost.
The new owners of the hotel quickly responded and were very kind. The previous owner had promised to notify everyone. This hotel may still be a good place to stay after they open June 4th.
Other RS recommendations were full, so we used Booking com.
