There are acouple of reasons for why I chose to go to KI in Stockholm, Sweden as a exchange student. As an example, it was because KI is really up to date in the Medicine world and world-known and also because I wanted to live in Stockholm.
The exchange information given by KI was really good and a big plus is that it was easy to get intouch with the people in charge of the exchange students if you needed help or was wondering about something.
