Skihotels in Oberhausen

"There is a lot of road construction around the hotel which means that I heard every sound all morning. That also meant that it took me 45 mins to find the parking of the hotel, when I booked I received a message that access to the parking is free due to road construction. Apparently the hotel meant that you can still use the parking, however the wording sounded like they meant its free as in no fee. Anyway, I discussed this with the staff and the guy who handled my complaint was extremely rude and even made a joke about me not wanting to pay the fee. He told me I had to call Expedia but Expedia told me I had to discuss it with the hotel which meant nobody helped. The whole visit he just gave dirty looks, no hello no nothing. Not very 4 star hotel service of him. My bedsheets had hairs on them and the whole room was extremely dusty as if it was an unused or just unclean room. I literally saw dust flying when I put down my stuff. The sink had some very weird mold on it so I didn't drink water from it. Very noisy hotel and the parking is so small that every car had to try 3-5 times to get out. I can imagine that it's a decent hotel for a worktrip but the whole experience for our little sistertrip was a 3/10. Highly would NOT recommend. And in case the hotel will respond: a 4 star hotel should handle confusion calmy and with a certain amount of service. This guy was so rude that I also got rude because I honestly couldn't believe the audacity. "
