I stayed there twice (1979 & 1980) in the officers’ transient quarters when visiting Berlin. It was a great place to tour Berlin from, using the U-Bahn. My wife and I used the Berlin troop train to get there from Frankfurt.
We had a unit there (the 690th ESG) I helped close. Spent many a night in the Bowling alley on the 5th (?) floor drinking Kindle Bier!
