I don't need to say much about the old town. It is really very beautiful. But somehow Gdansk remains my secret favorite. Maybe simply because I am slowly getting tired of seeing churches everywhere :-D
Historically, the city has the most to offer. Much more than I could visit in these few days. To get a crash course, I took a 3-hour tourist tour with a small electric car. As a result, I was able to see the old town, the Jewish quarter, and the old Jewish ghetto. Those who wanted to could visit the factory or museum of Oskar Schindler. Since I was the only one, the driver picked me up after 1.5 hours and gave me a private tour with some insider information. It was definitely worth it.
From the walls of Wawel Castle, you have a magnificent view. I actually only went up because I had time to kill on the last evening. But I absolutely did not regret it.
