Der Steiermark is a condo property that is listed on Hotels.com. I read reviews about it being clean, but dated. This was OK, as I just wanted a clean place to shower and sleep while in town to hike. Upon arrival, I could tell it was definitely in need of a "makeover." I was allowed to check in early, so I dropped off my luggage and explored town. I came back several hours later and noticed my eyes were getting itchy and breathing was getting challenging. It continued to get worse and was similar to what I experience when around cats & some dogs. Before booking, I had checked the Hotels.com listing and it stated no pets. So, I initially thought it was something else. As it continued, I researched the property and found the local property mgmt listing. It was very straightforward that the owner had pet(s) and warned that anyone with allergies should reserve elsewhere. The Hotels.com listing omitted this! I reached out to customer support that night and was told that I would be moved. After an hour passed I followed up and got nowhere. After 2 hrs, the local property mgmt txt me and said moving wasn't possible. It was now too late to find a new place, so I took extra allergy medicine and tried unsuccessfully to sleep. The next day, I spent the whole morning trying to get moved to a different condo. The property mgmt co. was helpful, refunding my 3 night reservation. After wasting 1/2+ day of vacation, Hotels.com reluctantly rectified the issues it caused. I booked elsewhere.
