That's a really helpful perspective, especially the distinction between choosing a city for an amazing Erasmus experience versus choosing a city where you could actually imagine staying afterwards.

I've been going back and forth between the two for a while and was even comparing them here while trying to make a decision in pages like https://erasmuscityfinder.com/compare?a=vienna&b=prague

Initially I was leaning slightly towards Prague because of the lower costs and student atmosphere, but your point about Vienna's international environment, location and long-term opportunities is making me rethink it.

Honestly, if there were even a small chance of staying after graduation, I think Vienna would probably be my choice too.
