This is not a free tour, but at 12€ it is about the same, if not less, than what you usually pay…read morefor a "walk first, pay later" type of tour. Our guide Seema is knowledgeable, and provides a lot of interesting tidbits along the way, without getting too much into history or detail. She is also well prepared, bringing along a book to illustrate the subject.
Really appreciate her suggestions of places that we can visit after the tour, as well as restaurants to try and local specialties to order. At the end of the tour, she stayed to answer any question the tourists have from where to get lunch to money exchange. We only did a day trip to Dresden, and this tour helped us get the most out of our day, so we could enjoy every minute of our brief visit.
