Pros (+) Staff and location were fine. We were happy to find at least this since we were late for better solutions.
Cons (-) We had a tiny room in the attic (15 SQM). Although we paid for the hotel in advance, only a couple of hours before check-out, they tried to use our debit card once again, but since it was not possible, they cancelled our reservation (curiously: they were probably afraid of our review at booking.com. Breakfast was okay, but nothing special. Some staff spoke neither English nor German.
