I booked both a twin room and a double room.
The twin room (Room 23) is fair, with table, wardrobe, cooking stove, a bathroom with tub. It is like a fair hotel room, wide enough to have a comfortable stay.
However, the double room (Room 19) is way too narrow. The living space is only about 2m x 3m. With the stove, a folding chair and a small shelf placed in the room, I don't even have space to put my suitcase, not to mention the bathroom.
Overall, the stay is fine, the stuff is so friendly. But I have to point out that the arrangement of the double room is a bit difficult to accept.
