The condo was attractive, but the persistent cigarette-smoke odor made our 13-day stay very unpleasant. From the moment we arrived, the unit smelled strongly of stale cigarette smoke and dirty ashtrays.We reported this on the first day, and the host told us the smoke came from the woman living downstairs. Several electric air fresheners and air purifiers were running, but the odor persisted throughout our stay.This issue was not disclosed in the listing. I am sensitive to cigarette smoke and experienced a cough and sore throat during our stay. Had we known about these conditions, we would not have booked this property. Future guests deserve clear disclosure before making a reservation.
