One of very few SPG properties in Germany that does not overstate its apperance, simply a nice, modern, true 4 star property with no ambitions whatsoever to be more.
As pointed out by other posters already, great upgrades to suites, convenient access by tram ( No.9 that also takes you directly to the Westin ) within 10 minutes from the main station. DM drug store, bakery, fruit&veggie store and butcher shop within the same complex, half a minute away from the hotel lobby.
Small gym and small sauna, decent hotel restaurant.
No free breakfast for Platinum members.
