Erasmus student looking for a place during the winter semester

I'm Hugo, a Spanish 22 year-old student. I've been accepted at CBS university for the winter semester to study Business Analytics and I'm looking for a place to stay from the 20th of August till December.
I'm looking forward to living in Cologne because it's an experience that I've never lived before and I'm ready for the challenge.
I'm quite extroverted but also chill and open-minded and I can adapt well to many situations. I love deep and meaningful conversations, as well as board games, having cheerful drinks with friends, both following and playing sports, and many more activities (I'm not really fond of partying, although I can go out from time to time).
