Entering unit, it was a strong moldy and musty odor. It permeated bedding. Opening doors and turning on A/C did little to help. A little exploring and we found mold spores in A/C and mold growing on headboard of bed. Notified rental agency immediately, but they took 14 hours to get back to us. We couldn't sleep well and were concerned about health risk to my wife who has asthma. Agency ignored our complaints, had no solution other than 1 night free. We still had to pay fees, and find another cleaner accomodation. Very disappointing.
