22 year old looking for accommodation in Cologne for the second semester 17/18

I'm a 22 years old history student from the Netherlands. As part of my studies I'm doing an Erasmus-exchange to Cologne starting the 1st of March. I'm looking for accommodation, either Wohngemeinschaft, studio or appartment.
I am a big fan of bord games and also practice swordfighting, so I will probably bring a (blunt) sword along. I'd like to meet new people during my stay with whom I would gladly go out for drinks or stay at home and watch a movie (or play a game ofcourse).
I try to be a clean roommate, which, as far as kitchen and bathroom (and other shared rooms) go, I'm rather good at. People also tell me I'm a good cook and luckily I enjoy cooking (both for myself and for others).
