Berlin hast two major international airports: Schönefeld (SXF) and Tegel (TXL). At both airports we will provide a pick-up-service all day on January 19th, 2018. If you arrive earlier or later, you need to plan the journey from the airport to the hotel yourself.
If you arrive by Train on that day, we will be happy to meet you at Berlin Main Station (Hbf or Hauptbahnhof in German).
Just make sure you state the correct arrival date / arrival place and flight number while filling in your final registration.
