It was fascinating to finally see the sites I've read so much about, & seen on tv documentaries for many years. We were a group of just 4 & our guide was thoroughly well versed & passionate about the subject. He encouraged us to offer views & was able to answer any questions. I've got a basic, self taught understanding of the subject & our guide was glad to fill in the gaps & tie everything together. There's LOTS of walking! There were a couple of rest breaks, one of which was at a pleasant street cafe for refreshments. I shouldn't forget to add that Matt(?), our guide, brought along a bottle of water for us all on what was a very warm day. I wouldn't expect this to be the case if we were a group of 15 or so though!

The bunker itself was a spectacle, however all of the information inside was very interesting, in a great chronology. Lots of info, although didn't over do it. I would definitely recommend getting an audio guide for this.

Alex was a great guide! Very informative and he gave us a ton of recommendations of where to go as well of where not to go. Thank you again for sharing a fraction of your knowledge.

This tour was very good. A very informative and enthusiastic guide, who gave a very detailed and interesting insight into Berlin life in the 1930/40s.

Great tour, very knowledgeable and likeable guide Martin who did a superb job. Great family trip that we will never forget! Thanks you very much
