We’ll meet outside the McDonald’s at Gesundbrunnen Station.
Look for your guide holding a sign that says: “Secret WW2 Tour.”
The station is called S+U Gesundbrunnen and is easy to reach by train or U-Bahn.
Please be there 10 minutes before the tour starts.
The tour will end at the Park Inn Hotel at Alexanderplatz. A central location with great public transport connections.
