Best Burghausen Hotels

First the positive: The breakfast buffet was rich and appealing with very nice service staff. There was a super great pizzeria and gelateria, which were on the ground floor of the hotel. We had a great evening there and the pizzas were just perfect and authentically Italian.
 The negative side: 
We booked three rooms. The rooms would actually be modern and nice. But no matter where you look: NOTHING was clean! The sheets/towels were changed, but I had the impression that the cleaning was not done at all or only very superficially. Dirt on the shelf, the ledge, lots of crumbs on the floor, chalky fittings, dirty toilet seat, mold on the rubber seals in the shower, dirty cabinets, doors, door latches. Worst: Dirty and disgusting duvets when you pull back the sheet. Something like that should be washed if it has stains. Disgust factor to the power of 10. I spend 8-10 weeks a year in hotels, but this was an impertinence that I had never seen before. At night: Loud bass music blared through the walls and floor until about 2am. Youngsters were in front of the window, which made noise until 5 in the morning. It was way too warm in the room. I am aware that the hotel cannot do anything about the noisy people in front of the room and the heat, but it was just crowning the rest. It was just horrific. We booked this hotel to recover from a long drive and drive more on the next day. Recovery wasn’t possible as we all couldn’t sleep. I will never book a Dormero hotel again. The term “fancy” they love to use means something completely different in my world.
