The city in Finland and you can feel -30 degrees sometimes in January or February. It has nice "nature" as Finnish people say but during the winter, you can not see that nature because of darkness and snow. You can see many students and many drunk people on the streets. The city is also famous with erasmus students
I was in Jyvaskyla last semester and I lost my room's key so I paid 20 euro just to open it.
In Jyvaskyla I fell down from the bike in the night because I was so drunk.
