room 121 is ok, but if your comingin for summer time or weather is a bit warm, you will want the AC running, this unit has somewhat really old unit, same for the heater if it even exist or work as the heater are those that installed around the baseboards and around the unit, you cannot sleep while the AC is on as its really loud, i ended up openingthe window just to let outside air cool the room latein the eveningbso i can actually sleep
