When I checked in, I reported a very bad odor in my room and requested a room change. That was denied because I was told the hotel was fully booked. No remedy was offered and nobody from the hotel investigated. This made me assume they already knew there was a problem. I turned off the air conditioning since that seemed to be the source of the odor. Unfortunately, the temperature was in the 90's. The window couldn't be opened to allow fresh air. When I checked out, the person at the front desk said it was a known problem with the air conditioning and the technician they had brought in couldn't fix the problem. It is unacceptable to charge money to live in stink when you wouldn't live in it yourself. The hotel is well located near the train station and the old town with lots of restaurants and shopping as well as lake access. Bottom line though is they don't seem to care about the customers.
