We're given a room that had a strong smoke odor, asked for another room and was given a room where the air conditioner barely worked. We ended up being charged for 2 rooms and no one can explain why. After 2 weeks was finally reimbursed one of the rooms (176) but they still don't know why double charge. We stayed multiple days and had to ask daily to get towels and garbage taken care of. The hallways have a strong odor in them and noticed our first night the non booked rooms were left open with windows open on our floor as if they were airing it out, so perhaps there was an incident. When asked about the rooms open and non of the doors on the building being locked if they were concerned about people simply walking in and staying in a room the front desk didn't seem too concerned. The 10 we saved each night is not worth this mess.
