The staff tells me that the duvet cover is not cleaned for a new visitor at all! while the sheets are for pillow and mattress, no such sheets are provided to duvet cover. That means u have to use some 2nd-handed to N-th-handed duvet covers!
The windows needs to be open wide to allow sufficient ventilation. I don't want to die of carbon dioxide, esp of lots of ppl in the same room - suggest to open the windows wide or install ventilation fans.
The toppest beds in the room have no wooden cover, such that when the lights are on, it is hard to sleep - suggest to add a wooden cover on the toppest beds.
This is impossible to book the rooms for a continuous time period e.g. one month. The available bookings of the rooms are often distributed. This makes me need to change the rooms once a while. This can be, in fact, solved when letting people to stay in the same room, regardless of the specific rooms (18-bed to 14-bed), as long as these room often have the same price.
