Like our school, in some dormitory buildings, a large bathroom is built on both sides of each floor, as well as two rows of sinks, many faucets, a cold water bathroom on both sides and a bathroom in several locations. Some rooms have separate bathrooms, which can be cleaned by themselves.
I've been to other schools and seen apartments. Almost a large apartment suite has a bathroom.
In short, you can't leave the dormitory. If you can't leave the dormitory, you will ... nonsense, even a single room can get a bedroom ~
Good luck meeting your type.
