A very rude man at the reception.
Booking not respected. A 20-bed mixed room instead of a 6-bed female only. Not enough keys for everyone, therefore, room door open permanently.
Only one shower for the whole floor, about 50 guests. Two WC, but one is impossible to use as the cover wouldn't stay up, but would fall down unless kept up by hand.
The staff OK, except for the man at the reception.
