only hot air will come out from the air-conditioning in the room. when we try to open the window to get some fresh air, we find out that the window are all locked and cannot be open. so, the room is hot and suffocating.
also, the room is small. we cannot cannot get enough room to open our suitcase.
worst of all, the partitioning insulation of the room is poor. we can hear the guy next room when he is talking over the phone, when he turn on water tape or when he close the closet door.
