This tour is definitely for history buffs or just people that are interested in finding out things they didn't know about the Third Reich. Our guide did a fantastic job, it's a very short bus ride from the Zoo station to the Reichstag building, that's where the tour begins so make sure you have bought a transport ticket and validate it!!
our guide was arya she made the trip really interesting . the only reason i dropped the 5th star was because of the lack of a loo break.[we did get one eventually].not for myself but i watched other people on the tour struggling with no loo break then almost being left behind when they had informed the guide that they needed to go,we suggested that everyone should go and we were told we'd be taking a coffee break very soon[an hour later]. the trip was well worth doing to get a feel for berlin but i hope the above complaint is addressed for other tourists.
