Thank you for your feedback. From the information you shared, it sounds like you went on our group tour but mistakenly posted your review to our private tour section. We offer private tours for people, such as you, who don't want to be in a larger group and who wish to tour at their own pace. However, from your review it seems like you chose to do the group tour instead. There are limits to what we can offer on a group tour priced at €29. Seventeen people is not really considered large for a group tour. As you point out, our tour guides do indeed sometimes turn their heads from left to right as they talk in order to try and address everyone in the group. Very sorry if Achim addressing other people on the tour was inconvenient for you. As far as the pacing of the tour, we try to show people as much as reasonably possible within the time frame of a 4-hour tour.
