It's alright for a couple of days if you don't have a lot of money, but I personally did not feel that safe. Someone from my room stole 80€ from me while I was asleep, because my locker was broken and I could not lock it. Also the bed wasn't comfortable. Plus I always (even during daytime) heard someone snoring/coughing/whatever from a corner where there shouldn't even be a room behind the wall, based on the sizes of the rooms and the building in general.
