Totally unacceptable. AC unit was broken. Reported it at 10pm when I checked in. Supposedly was going to be fixed by the engineer at 11pm. Problem never fixed. Went down to the desk for a third time at 2am and complained. They said all they could do was provide us with a fan. It was a tiny 1ft fan. That did nothing for a room of four people in separate bunks! It was very warm and humid all night and I barely got any sleep!!! The staff wouldn't even move me to another room or do anything else to help. Don't think I'll be returning as this did not seem like an urgent issue to the staff despite me talking to three different employees.
