We had a limited amount of time in Berlin and Markus was terrific in making sure that we saw all of the key sites. One of our group of 4 had never been to Berlin so Markus was careful to show the key "tourist" spots as well as introducing us to some new, cool areas of the city for those who had been before. The highlight was the way Markus went way above expectations to find the areas and exact house where one of our group had lived as a teenager 40 years ago. This was very special. Thanks, Markus!
