Like some other reviewers I picked up a leaflet from a guy in the street, who wasn't at all pushy. They don't pick you up from your hotel like some of the other operators who, understandably, charge a lot more. Their office is, however, very central in a little alley only a few yards from the main square. We travelled in an air-conditioned minibus to Auschwitz so the small number in our group made it a more pleasant trip than the big coaches used by some operators. The video we were shown on the way prepared us for the harrowing experience of the visit but nothing can compare with actually being there. It's not something you enjoy, but we were glad we went. We were so pleased with the service that we booked Krakville Tours to take us back to the airport which, again, was cheaper than quoted by the hotel. Our driver this time was the owner, Piotr, who was very informative. Wish we'd known about this company for the trip from the airport to Krakow!
