You can typically cool the unit(s) down by propping open the front door and slightly opening the balcony door. All units have ceiling fans and box fans. The unit(s) tend to cool down nicely in the evenings. There are a limited number of units where the owner has purchased a portable AC unit that is installed in the living room. Please see the listings description to determine if that unit has a portable AC unit. (NOTE : Portable AC units must be vented through an exterior wall and SHOULD NOT BE MOVED).
