Krakow does something unusual on this list: it makes Western Europe feel expensive again. A furnished 1-bed in the old town costs about what a single room runs in Zurich, and the city is dense enough to do everything on foot. Welcoming people, a strong student-city vibe (one of Europe's oldest universities is here), and proper Polish food — pierogi, hearty soups, fresh bread. Same timezone as Switzerland, full Schengen, four real seasons including a winter that's genuinely cold. Trade-off: the November–February grey stretch is long if you don't like that kind of weather.
