Do not stay here

My wife and I entered our room at 10:30 pm Thursday night, and within a few minutes she was experiencing an allergy attack from the smell of mold or mildew. She went to the car so that she could breathe, and before 11:30 pm I had finished repacking and we were gone.

I left a note politely explaining what happened (and that the bed was not used) and was not contacted. I contacted them later the next day, and the owners were gone for the weekend. The cousin who was left in charge said I'd have to wait until the owners returned. I called them on Sunday when they had returned and the owners treated me like I was trying to steal from them.

I would have been satisfied with a partial refund, and would have left a positive review despite my bad experience, but instead the owner hung up on me while I was speaking calmly. They had angrily claimed that the smell was not mold or mildew but instead the cleaning agent used. They refused to do anything because I had already payed at 4pm on Thursday.

The closest thing to an apology I got was, "You should have told me that your wife was asthmatic, and I would have told you, nothing against you or people with asthma, but I have to keep my rooms clean so I use cleaners, and you would just be happier if you go somewhere else."
My wife does not have asthma, she's just recovering from cancer.
Neither she nor I noticed the smell of cleaning agents - the sheets and bed smelled clean. In fact the mildew smell seemed to come from everywhere but I couldn't smell it in the blanket or sheets or pillow.
My wife and I have stayed at many hotels, motels, bed & breakfasts, and inns, some with more stars some with less, and regardless of the accommodations, the owners and staff have always been more reasonable than the owners of the Sun Valley Motel.
Do not stay here.
