This was a unique experience. The beds was more comfortable than my own at home. Each dorm bed received loads of towels, a hair dryer and slippers and a safe within the assigned locker. Breakfast on the roof is expensive but one of the best I've ever had. Service was incredible. Location was perfect. The only negative is that the hotel doesn't have a lot of common space, even for regular guests, and the dorm rooms do not have place to sit, making it tough to have downtime when you are awake. This is OK because there is so much to do in Vienna. I wish I could have stayed here longer.
