This is a beautiful location. The history of the area is well-preserved in the carefully cared for houses, cobblestone streets, bike paths and beach. The hotel is beautiful and well-run. Very nice staff - however, everything is written and spoken only in German, so if you don't speak/read fairly well, this may not be the best place for you. There is a country-club feel to this hotel, and the other guests (or members?) did not like having foreigners here. Despite what guidebooks say, being polite, knowing a few words & phrases and keeping a low profile will not get you by - you really need to speak German.
The location is great. Service, Spa, Pool and Breakfast is very good too. The Hotel rooms ( 4 Star Hotel ??) do not have air condition system.Not acceptable in hot summer months.
