Potsdamer Str. 58
Please note that there are several "Potsdamer Str." in Berlin! The right
one is close to Potsdamer Platz, bus stop "Potsdamer Brücke" is in front
of the building, .
A few steps down lead to the main entrance. Ideally use the right door
(if closed please ring the bell) and take the elevator to the 7th floor.
Also note that those who want to join the "Vorabendtreffen" of the APF
meeting should have registered via the APF site for the APF meeting.
