Sebastian was great! Our day was like touring with a friend. We talked about a lot of things while driving to Marlboro Castle (awesome site) and learned about life in Poland, history and current trends. Lunch was at an amazing restored historic home that had been moved 60 km; the food was excellent. We added a beach visit to a real Baltic beach (did not find amber) before taking a short ferry to Westerplatte. A great day with an outstanding tour guide.
