If you are going for cultural experience... I'd suggest Czech republic is a good choice... dynamic and thriving post-transition society. Which school and what would you study? I know Erasmus students are quite satisfied with the english programs on Charles and Masaryk's universities.

However.... if you go come here... STAY FAR AWAY FROM THE HEALTHCARE. Take care of those things home and STAY AWAY. It's not even bad as the competences go (although it varies a lot), but Czech doctors are very entitled and rude and unpleasant (and often expect bribes). And often don't speak English (yeah, there are MH experts in Prague and Brno that speak English.... but they don't speak it for free so it say).

Outside of that.... it's safe, relativelly cheap (although Prague...not so much anymore). THere's also a load of foreign students on our Unis, so you can lean on each other for dealing with the culture shock.
