The workshop takes place at the main campus of Wuppertal university (Campus Grifflenberg).
Detailed directions on how to get there can be found here
. From the station, you may take
Bus 645 (direction Küllenhahn, Am Burgholz) or 615 (direction Remscheid, Fr.-Ebert-Platz) and get off at the stop "Universität".
The sessions will be in room B.06.01 which is located in the rectorat's building: when you get off the bus,
pass the main building on the right (down the driveway). After about 100 meters you will see a modern-looking building with blue window frames and corrugated iron front (Wellblechfassade...). This is Building B, and we're at level 6, which is the ground floor ;-).
