Esper was very pleasant, knowledgeable, and took us to places we would never have discovered on our own. The 300 steps up the tower were challenging, but we were rewarded with spectacular views at the top. Highly recommend this tour.
Dennis is a top rate guide! He showed us exactly what we asked for and we had a great time.
Mark was an excellent guide. He had a tremendous knowledge of Berlin and was able to answer questions and show me really interesting aspects of the city. Very professional, friendly, and willing to adjust the tour for my specific requests. Highly recommend Mark. 5 Stars!!
