Thank you for this review. We are sorry to read that you found the tour to be "a bit disappointing". Our guide met you three at your hotel as planed and started the tour from there. Then during the tour it was decided not to finish the tour back at your hotel, located outside the historical center, as that would mean a 30 min trek back there and would surely not be a valuable use of your time with the tour guide. That is quite normal. 'Drop-off' is optional and the vast majority of guests decide, as you did, to finish in this historical center. It was your tour and our guide was in discussion with you throughout about what you wanted to see and which themes you wanted her to expand on. We can spend any amount of time at each site, but we are also expected to deliver a complete tour. During this tour we tell the story of Berlin, helping guests to 'understand' Berlin while visiting approximately 16 of its most iconic sites. The only real fixed constraint we have is time, and unfortunately it always runs out.
Thank you for touring with us.
