Excellent tour. Highly recommend for anyone who would like a detailed explanation of all the sights, and history of the locations you're visiting. The guide was very informative and spoke good english.

This is good just to skip the line at Eiffel tower. Everything else you can do on your own. So if you can get tickets to Eiffel tower without staying in line then this tour is not worth.

Liked the tour a lot. Covered the whole Potsdam in one day and got a nice workout as well.

This is an excellent tour. I loved it. Covers the whole city of Berlin, sights that are a must see. Probably should do this on the first day of your tour so that you know where you should spend more time in rest of your visit.

You're better off doing this on your own. The entry to this camp is free and there are some guided tours available or you could get the audio guide for a small fee. Our tour guide was too fast and we didn't have much time to take pictures or read the descriptions.
