Our room's heating does not work!!! The room is cold in the midnight and we can't sleep well even wear lots of clothes and a jacket. How can we sleep in a no heating room at the end of December? On the other day, we told a staff that our heating is really not worked. She just closed and opened it again, and then using her hand to touch the heating said it's work, and she could help nothing on it. But it's just warm itself, not really warm actually, it must not warm enough for the whole room. It is absolutely unacceptable!!! Finally, we just requested to get 4 more blankets for the last night. Luckily, we just stayed 2 night.
