Rooms are somewhat smaller than normal which, in summer, makes them feel a bit oppressive, even with the balcony window open. Beware, everything is chargeable, especially car parking. The car park is very small (about 20 cars) with an overflow a few minutes' walk away down the street; be preared to drive up what looks like a pedestrian street to get to the main door to drop off any luggage. As usual in Germany, the buffet breakfast is substantial but the layout of the dining room/bar area means there are bottlenecks where you are continually side-stepping other diners on the way to and from the buffet. And on one night, the sound on the only English TV channel stopped working, for no apparent reason. Although one of the receptionists came up to have a look at it, she obviously hadn't a clue and there was no maintenance man on duty at the weekend. Finally, no tea/coffee facilities in the room, a bit of a prerequisite for 4 stars, in my opinion!
THe hotel couldn't be better placed - directly across the (pedestrian-only) promenade from the beach, its own Strandcorben available to rent by the day/half-day and only a 5-minute walk to the pier, where most things seem to happen. Very helpful staff were quick to respond to requests, the bed was one of the most comfortable I've slept in at a hotel and the breakfast choice was enormous.
