I choose to do an Erasmus because I often heard it was a great experience and thus I wanted to live it! I did not really choose to go in Sweden because in my school, you choose to do an Erasmus but not where you go and for that type of trip it was Sweden or nothing. I was ok with that. I mean I did not know Sweden at all and discover new place is also part of Erasmus so I actually was very excited.
I also learned that the university, KI, which I did not know at all so far, has a very good reputation which made that trip even more interesting.
I had no problem to find the informations I needed on KI website and I also had enough information from my school.
