What is a hotel economy room?

Hotel economy rooms are cheaper rooms in the hotel. Some may have no windows or windows close to the corridor, or may have lower floors. Each hotel is different. You can consult the hotel for details. A double bed room usually means a room with a size of 1.5*2m/1.8*2m/2*2m; a standard twin room usually means that there are two small beds of 1.2*2m in the room.
