I booked a room online. When I check in, the staff told me the room has no window. She ask me to pay extra 150 RMB per night if I want to switch to a room with a window. Why when I book online, the detailed room information doesn't say that the room is without window, then ask me to pay for extra to switch to a room with a window when check in.
If I knew that room is without window, I would not book that room. I hope the hotel give out the information on line about if the room with a window.
