I've never done anything worse. We had to change room twice, at first the gave us completely wrong room, second they gave us messy room under contruction and all this in 5th floor with broken elevator at 11pm.
It was impossible to sleep during the night because the other guests were super drunk and noisy, even we had private room. There are thin walls so you can hear absolutely everything, even if someone is just walking.
I can't recommend this.
