Not only students but also company employees seem to adopt this style.
Mostly there are some small individual rooms, common WC, bathroom and one big living room.
I think it's very exciting because many friends are together there
and they can help each other in the case of difficulties.
However if there are ten persons in a small room, it may be too exciting to live in.
I think it's almost nonsense as a room
but for early some days it can make the residents laugh very much.
