The house is on the ground floor of a house. The house has only one bathroom, no dishwasher, washing machine, and dryer. The windows of the room are relatively low from the ground, so the owner uses three indoor air machine to input air, but my husband has allergic rhinitis. the indoor air makes he difficult to breathe. When we opened the window, we found a lot of dust on the window sill. We immediately reported it to the owner. Although the owner finally provided a compensation of $40, we were very unhappy. We don’t want to come back.
