It is hot because all the air conditioners can't run or one of the circuit breakers blows. This makes the loft room unusable. Make sure this gets fixed before renting if you need all the space. This applies to the loft and common area. The rooms can stay on and the doors closed so they cool off. One of the room's AC is on the circuit that blows. There are 4 AC's on the circuit that blows constantly and only 1 or 2 can run at a time depending on the other loads at the time.
