Just a travel day today. We got on a train in Garmisch (about 200 m from the apartment) and took it all the way to Munich. A 30 min transfer in Munich had us on our way to Berlin in facing first class seats. Went through all sorts of towns and cities, including Erfurt and Leipzig. Unfortunately the train didn't go through Halle, where my grandfather was born.
A quick tram ride to East Berlin brought us to our AirBnB for the rest of the week. Sure can tell the difference in architecture between Munich and the old East Germany.
