They're totally correct on that! More ferners in FRA than Krauts. Sucks!
My prospective (it was my first location upon joining the AF)...Frankfurt has a great Metro...used to be utterly safe (won’t say that today)...and the Sachsenhausen district used to be the best beer pub area in Germany. Today? The power-players that work there...pack up at 5, and leave for homes way outside of the shadow of Frankfurt.
