We stayed at the 3-bedroom unit, where 1 bedroom is located at the mezzanine. AC in 2 rooms located at the lower level did not work well. It automatically turned off after 1 hour of usage. We called the technician at 2 and 3 am and he fixed something at the balcony, then the AC functioned again, only for another 1 hour. Rooms were so stuffy without the AC so we decided to stay at the living room, sleeping on the chair and sofas.
