Fantastic tour guide! Lukasz was available to answer questions and customize our tour before we arrived. His way of sharing historical information is interesting and never dull. His knowledge of the area is immense. Further, he navigates through road construction and festival related street closures with ease - and timed our trip with no overlap of other groups at the largest attractions. Moreover he helped us get all of the artisan amber goods we wanted... and got us back to the ship on time!
