Go to bed and get off the table, a room for four. Each floor has a large bathroom and laundry room, and a dormitory area has a grand duke bathroom. The air conditioner can be installed by itself, just apply. There are restrictions on electricity consumption in dormitories. It is forbidden to use high-power electrical appliances, which will trip. But it turns out that as long as four people don't use it at the same time, it's no problem to use it separately. Good wishes!
