This tour was excellent and the tour guide was the best we had for any of the trips we did during our visit to Krakow. The guide was full of interesting information and spoke excellent English. He spoke clearly and guided the group around at the right speed so that we could take photographs and have a good look at everything. The tour was very reasonably priced and the guide was clearly passionate about the subject. I didn't catch the guides name but he said English speakers usually call him Jack. I would highly recommend this tour.
