Took me almost 1 hour to open the the door to room 7. Completely busted. And this was at 10 PM, so the risk of not having a place to sleep was real. Took them 1 hour to reply and apparently you need to shove the key SO HARD that you hand will fall off. Other guests also tried to help us open the door, but they similarly failed. So it wasn't just us! Upon entering the room, you'll be greeted by a boiler that makes as much noise as a steam locomotive. So don't expect to sleep much. Maybe if you get another room, you'll have a better experience.
