We have been on the camp site for 3 nights with private bath. The last night, the pipes were blocken, water did not flush anymore in shower and toilette, but the Rezeption was not able (or willing) to call an sos plumber to fix it, as it was 6pm. This is sad... as there are not public toilettes or showers on the camp site...
