FKK club in Frankfurt Hausen, used to be called FKK Paradies. It's located in the North of the city close to the Frankfurt Messe and a viral Autobahn exit. Very easy to find once exiting Autobahn Wiesbaden-Hanau on Frankfurt's Nord-West-Kreuz. It's cozy and easy going and more of a intercourse-intense-factory than a place to relax. Compared to other FKK clubs it is moderately priced.
