All rooms are single rooms.
Normally, students stay in their rooms over the vacation periods. The rooms are slightly different equiped. In general there is no problem to get a room equiped with a refrigerator, sheets, pillow and blanket or sleeping bag, plates, cutlery andcooking utensils. Mostly the kitchen is shared between two or three students.
