20 year old American student looking for a room in Madrid, ideally close to universities

I'm an American student (fluent in English, learning Spanish), I will be studying at Universidad Complutense de Madrid. I'm really laid back and I can get along with pretty much anyone. I love hanging out with friends and I can't wait to meet so many new people! I am clean and respectful, I have been living with roommates for 4 years now. I love sports (specifically soccer) and working out so I plan to go to the gym a lot. My ideal roommates would be respectful of personal space, but most importantly, people that want to go out and explore the city and the rest of Spain. I would love to have people to go out with and stuff, as I will not know anyone there. Look forward to hearing from..anyone haha.
