Just a quick feedback - whenever I stay there I get regular room on the higher floors, somtimes on Executive level or otherwise at one level below. Lounge is OKish compared to other lounges in Germnany and can be pretty full at times. Beer and wine is complimentary at some time in the evening, soft drinks and water also beyond that.
As to getting there uber is no option as they do not operate there at all, you can either take a combination of trains and busses or a regular taxi.
