21 year old male, looking for accommodation in Copenhagen for the fall

I will be a exchange student in Copenhagen this fall (September 2017 - January 2018). I am a 21 year old male from the University of Wisconsin, Madison. I am looking to share a flat close to the center of the city with people similar in age to me. I am studying physics at my home university, I enjoy sports like rock climbing and snowboarding, although I am a fan of many other sports, especially American Football. I speak English and Spanish, but I don't know Danish (trying to learn). I am looking for a roomate, or roomates who try to be clean, and open minded. Roomate gender does not matter.
