The first night we arrived, there was a strong smell of mildew, it was musty, and felt damp. It was very late at night so we couldn't go anywhere else. I wrote to Jason with the problem, and he told me that it was probably an air filter issue and that he would fix it. The next night when we returned, the apartment still had the same smell and musty feel. When I looked around the bathroom, I saw a very large yellow spot on the ceiling of the shower -- what appeared to be mold. The shower curtain liner was also disgusting with what also appeared to be mold. There was also no vent in the bathroom -- just a big hole where the vent was supposed to be. It also looked like the kitchen hadn't been thoroughly cleaned.
Jason was helpful in getting us a refund the second night so we could go somewhere else the second night. But I still had to reserve a hotel room, pack, and get an uber to another place in the middle of the night.
