Student looking for accomodation in Cologne

Hi
I am a Norwegian student who will live 7 months in Cologne (January to July)
Will study at Cologne Business School which has its Campus in Neustadt Süd.

What I was wondering if there is anyone who can recommend a place to live or which area is good?
I like to go  jogging in the morning and also prefer a gym close by. Bars and clubs, centrum or just a place where there is life is also preferable not too far away :)
Can travel 15 minutes with public transport to get to Campus that's not a problem. Heard cologne is good for bicycling also.
Appreaciate all inputs ! Budget 300 to 500 Euros a month.

just have a look at wg-gesucht.de if you would like to live in a flat community.

According to the area take a look at Ehrenfeld, Neustadt Süd, Sülz and Lindenthal.

Thanks! Will have a look :)
