Hi Zverka,
If you are looking for an internationally-accredited University, I’d suggest you to take a look at University of Padua, Physics department:
http://www.fisica.unipd.it/
Padua is really lovely, normally hosting over 67,000 students. Many of its graduates are employed by renowned American and British Universities.
I guess that if you are looking for a period of your life that joins fun and career, Padua could prove to be the right place.
Hope it helps,
Johnny
