We booked a private room, there was no lock on the door and the AC is shared with the room next door. The rooms were separated by a very thin metal wall so you can hear everything, we were woken up every night as people came back to the hotel. We even had people randomly walk into our room multiple times! The 2nd floor has a dorm room with 10 beds PLUS 2 private rooms and all share ONE bathroom and 2 showers. Something just doesn't add up right does it? The building smelled bad as there is a shrimp restaurant before entering the hostel and the lobby smelled stale and dirty. Staff were very inattentive and sat on their phones most of the time while the bathrooms remained filthy, covered in hair and large cockroaches roaming around. We are very familiar with Chiang Mai, and this is by far our worst experience! I would not recommend this hostel at all.
