We stayed at Hotel Imperial on the isle of Rügen for two nights and didn't regret our decision at all. The house is located at the famous beach promenade of Binz just a few steps from the beautiful sea.
Since all rooms facing the sea directly where already booked we choose a room at the side of the building instead, but still had a very nice view of the seaside from our balcony, which was small but clean and beautiful.
The staff was very polite, professional and friendly. The breakfast included in the price for our room was good, but nothing extraordinary. A very nice service was a daily printout you could find at each table every morning, detailing various events and activities for that particular day the hotel was recommending (rides with the special historic local train "Rasender Roland", comedy shows in the evening etc.). One thing I didn't like about the breakfast was that it seemed to be mandatory. If you plan to eat somewhere else there doesn't seem to be an option to book the rooms without breakfast.
The prices of the rooms where quiet high, but given it's location that was perhaps to be expected.
As a conclusion I would say this hotel is definitely worse a recommendation if you want to relax at a nice and warm hotel near to the beautiful seaside of Rügen, even though it's a little pricey.
