We stayed one night in a room for 4 people. When we arrived we had to call somebody, since there was nobody at the reception. Finding the room was not easy, because our room didn't have a clear numbering. Then it took at least 15-20 min until I could get somebody again on the phone (the room didn't have any bed linens).
The room was in the basement of one building and also quite dusty and noisy. Facilities were very old. Due to the dirt in the room and the strange smell in the main building we decided not to take any breakfast there.
Finally I had a long discussion at check out, since they wanted to have additional ~33 Euros for the bed linens. Since this was not clearly stated on the web site, a clear "no go".
