Take the A4 and exit at Klettenberg. Drive towards the city center up until Militärring and look out for the sign that says "Geißbockheim"
Note: GPS users, some GPS systems will not recognize Franz-Kremer-Allee. In this case please enter Berrenrather Straße 549 into your device.
Take the Line 18 from the Hauptbahnhof to the Klettenbergpark station. From there you must walk approximately 10 minutes towards the crossing of Militärring and Berrenrather Straße. Look out for the signs that state "Geißbockheim"
