Host, asked to switch our unit one hour before we checked -in to another apartment, (they mentioned that the A/C went out) the new unit was far worse than the one we booked. I contacted them apon arrival, told them I was not happy with the place since, It smelled like someone was smoking in the apartment, along with being located across from a parking garage (very loud) we also found stains on the sheets and pillows along with what looked like mold in the bathroom. Host, also was not great at communicating, I got a lot of what seemed like automated messages when asking questions before the trip.
