I'm just curious, but why Poland?
My first choice was actually Berlin. My main foreign language in gymnasium (high school) was German, and a semester i Germany would be a good opportunity to freshen up my unfortunately now quite poor German-skills. But there was only one spot for a student from my university and I didn't get it.
My second choice was Warsaw. To be quite honest I don't know much about Warsaw or Polish culture because I've never been there and I don't know anyone from Poland. But I have a feeling that Poland is an exciting country to be in right now because of the changes that (I heard) are going on economically. The average Dane knows close to nothing about Poland (or the Czech Republic or other countries from Central-Europe) and I think that's a shame, because I feel that theres a lot to be discovered. Am I right? :)
Also, as I mentioned before, my mother is Czech, and I have a very close relationship to the CZ. I think and hope that I will recognize some of the things I like about the CZ in Warsaw (like the food ;) )
