Berlin fully booked? Erkner is on the RE1 and S3
From Berlin to Erkner – on the RE1 or S3
Berlin fully booked or too expensive? Then it's worth looking at Erkner, just over the city boundary. The RE1 regional express is the fastest way into the city from here, and the S3 runs with no change to Ostkreuz, Alexanderplatz and Hauptbahnhof. There are three furnished apartments here with their own kitchen, from 35 € per person per night.
