The tour, guided by Bernhard, was the best part of our stay in Berlin. We were four adults. Bernhard was knowledgeable, easy to be with, obviously enjoys what he does....couldn't have asked for a better guide. The van was driven by a wonderful man, Wolfgang, and it was a help to have the transportation taken care of. Berlin is a sprawling city with historic sites located miles apart.
If you go to Berlin, book with Humboldt.
