I spent a night here with my colleagues whilst staying in the Hague. They had a really nice chill out area outside where you can hang out with your friends and have a chat. There was a fireplace on the table which was welcome as the weather wasn't that great. The bar was nice too and there was lots of space around to relax so you didn't have to be in your room the whole time.
The dorm room was okay, but it got so hot in the night that I kept waking up. It was a comfortable bed though, could just do with some aircon - or sheets instead of thick duvets in the summer.
