We stayed here for about 10 nights during wintertime, and heating and hot water worked impeccably. The hot air heater whirled up a lot of dust, that made us quite allergic from day one, it should not be necessary in a room with no carpet to have such a high level of dust (as seen on furniture after a few days). There is a tiny gym on the top floor, with a sauna we didn't try. The soundproofing is not good, I slept with earplugs. Otherwise the hotel is nice, helpful staff, and the food is good. Just that it is hard to get: The room service menu is very limited, and service stops sometime around 10 p.m. The different food service schedules are hard to grasp in the beginning, the breakfast personell refused to have us at 10:20 a.m. while the service was announced to stop at 10:30 all days. Dinner is announced in the elevator until 11:00 p.m. but in reality the kitchen doesn't make any food after 10:30. The weekday dinner buffet stops at 10:00 we learned, it was still there when we arrived at 9:56, but they wouldn't serve us. My advice to the hotel administrator: Make one simple schedule that is easy to understand for your clients, communicate it, stick to it like Swiss would do, and we don't care how much time after that your people need in order to clean the kitchen!
