Yesterday, I ordered 1 superior twin room and 2 AC cabins.
It turned out that when I checked in, I got a cabin without AC, the AC was outside the room, aka in the corridor. When I was going to enter one of the cabins (around 10 pm), it turned out that the room was occupied by someone else and smelled of cigarettes.
For the superior twin room, overall it was okay, for that price.
