I was first assigned room 325, upon entry the room was freezing. I immediately attempted to turn off the AC unit, but no luck. I turned the thermostat up, significantly then left to eat. When I returned, the room was still an ice box and even though I changed the temperature, the unit was still blowing out freezing, cold air. I went to the front desk to request another room. The front desk staff was excellent and I was moved to room 301. Unfortunately, the same issue occurred with the AC unit, and rather than move to a third room, I figured out how to unplug the HVAC unit (which was no easy task). The hotel rooms smelled heavily of paint and construction materials, as did the hallways so I surmise that the rooms were pumping out AC to overcome the construction odors. I would like to point out that the staff at the front desk were excellent but thankfully, I had a close friend close by and slept at her house rather than sleep in the hotel room.
