There were two reasons for this: 1) the walls are very thin and not sound-proof and our neighbours were partying till 5AM, we had to tell them off in the middle of the night, and 2) there is a piece of glass on top of the door and if someone walks outside in the hallway, the lights automatically turn on and our room gets lit up because of the glass. There were many people walking around from midnight to 2-3AM and we couldn't sleep due to the light coming into the room
