This tour was fantastic. We met up with our guide at the allocated time and place, and were delighted to find that the guide was a fellow Australian. Immediately we built rapport and the jokes started to flow. The tour is comprehensive, particularly doing it on foot. It was paced really well and Steve (our guide) had comprehensive knowledge of Berlin and all of the sites he took us to. This type of tour is awesome as you get the knowledge and detail that you might miss otherwise, which in a City as rich in history as Berlin, is so critical. We walked for almost 7 hours (with breaks for various drinks, bathroom and food needs), and did about 12km in total on the day. We were really pleased with the quality of this tour, being a private tour it gave us flexibility to go at a pace that suited us, and we felt we learnt so much about Berlin and its history. Steve added great colour, humour and storytelling to the tour which really made it a lot of fun.
