No, I flew at Lübeck, northern Germany, via my university sports department back then. One of the few commercial gliding schools in Germany. Kind people and good place.
A two week absolute beginners gliding course (up to solo if you pass like 50 very short flights) is below some 1000 Euros (plus living and accomodation) I lived in a wooden hut on the airfield back then. After two weeks I could solo for short flights around the field under supervision of my instructor on the ground. Spectacular fun. You get towed by a winch. It's a long field so you gain some good height.
