I stayed in room 301 one night recently and found the air conditioning in that room to be faulty. I kept lowering the temperature, eventually getting it to 21 degrees Celsius, but it still felt hotter than my home at 28 degrees Celsius, making it very difficult to sleep. (When checking out, I peeked into a double room on the second floor that had already been vacated and it seemed cool; it appears only room 301 had the air conditioning malfunction). I didn't complain that day because I arrived so late and worried that complaining might disturb the owner's rest, so I didn't say anything. Aside from the air conditioning, I had no other complaints.
