The Steigenberger Hotel Sonne in Rostock is one of the nicer hotel properties in Rostock. Located directly across the street from the city's famous marketplace, a tram station, and the mouth of the city's pedestrian zone, the hotel is well situated for both business and leisure travelers. Rooms are a bit on the small side, but have nice amenities and are furnished in a sleek yet homey modern style. Many rooms overlook one of two busy streets. Especially in summer, when you're likely to have your windows open, the noise from the street and the restaurants below can be disturbing; it may be worth asking for a room that is not on the main street side. The breakfast buffet is wonderful--typically German with more choices than you can shake a stick at--and the restaurant and adjacent wine bar are fun, lively, and serve pleasant, if not earth-shattering, cuisine. Staff can be a little wishy-washy; when I checked in with piles of luggage, no one offered me a hand at the door or up to the room, and when I asked for assistance, the staff at the front counter seemed put out. By German standards, however, service was fine. I certainly prefer this hotel to the Radisson SAS because it is smaller and more intimate and I think the location is more convenient and charming. Also worth investigating for the more budget oriented traveler is the Hotel Kleine Sonne across the street. I haven't stayed there, but have been inside, and this seems like a very friendly, reasonable place directly across the street from the Steigenberger Hotel Sonne.
