We enjoyed our stay at the Hotel am Schlosspark. We bought it as a last minute spontaneous decision and had maybe expected a discount (which we didn't get) but when we arrived we found check-in polite, extremely quick and free of any bureaucracy.
The room was large, comfortable, very clean and tidy. Walking from the hotel to the city centre near the inner harbour was easy and short. The buffet breakfast next morning surpassed our expectation: fresh juices, fresh fruit, cooked breakfast on request, good coffee. And again at reception check-out took less than a minute.
