I CANT CHOOSE!!! SPAIN, CZECH REP, or CHILE?!?!?

I would choose Chile personally, because I already live in Europe so in theory, could go to the Czech Republic whenever I want. You would also get to improve your spanish in chile, which looks good on the CV. However, I know that C.R. is beautiful and I know some Czech people who are really nice. You also have the bonus of being in Europe, so you have easy access to all the other European countries. But it's colder in the C.R. than it is in Chile, so that might be a factor you have to think about. What are the courses like in each of the countries? That should be something to think about, because you don't want to be overworked, or bored with the subject, etc.
