We had limited time in Krakow and wanted to make the most of it and was able to locate an amazing guide, Monika Prylinska . She's not in Rick's book but works for Krakow Urban Adventures and her phone # is 48-693 648 528 and you can text her. She met my husband and I at our Airbnb and helped us figure out how to pay for parking (and actually paid for it!). She was incredibly knowledgeable about all aspects of Krakow enthusiastically and clearly answering my questions. There is no way we could have appreciated all this amazing city has to offer without Monika's wonderful tour guide expertise. I cannot recommend her highly enough!
