18 year old guy, language student, looking for accomodation in Cologne

Easy going, quiet and respectful. I'm open to different types of accommodations, be it a flat or a dorm or anything else. My only condition is no shared bedrooms, anything else goes. I'm roommates who are respectful and peaceful. Preferably somebody who speaks english or spanish so that we can communicate effectively and get to know each other moderately well. We can keep each to ourselves or we can become friends, both are absolutely fine by me.
