Vienna, Austria. It has been ranked the most liveable city in the world for some years in a row. Cost of living is low compared to the European average; you can rent a medium-sized apartment for 600-700€/month. Everyone speaks English. Co-workers from Spain never bothered with German, because they can get anything done in English. Viennas public transport system is cheap (30€/month) and excellent. You can get anywher…
My sister lives there (though she doesn't work in tech) and massively prefers it to Budapest. Her main issues are that the summers are hotter than she find pleasant and that politics is moving in quite a right-wing/anti-immigrant direction (the latter was also one of the reasons she moved from Budapest).
Seems to be a global phenomenon. Is there a place where this isn't happening?
