The first night we stayed, the neighbors were very loud, and it was around 2 a.m. The sound of people walking and climbing stairs was very audible. Most surprisingly, the second day when we returned to the hotel, and when we unlocked the room, we found that there was another occupant in our room, and the hotel had not informed us that our belongings had been moved to another room. And in the new room, the AC was leaking, as in the photo I uploaded, but only a small amount was left when the leak occurred (I was too late to take the photo).
