20 year old guy, looking for accommodation in Frankfurt, Germany.

Easy going traveler that is studying in Frankfurt. I am very active and try to stay busy at all times, but thoroughly enjoy time with friends or playing sports. I also speak German and Spanish and am always looking for opportunites to travel! I would be interested in a furnished apartment, alone or with roommates, and would like to stay there as long as possible during my studies. Preferrably would like to be in the city and not too far away, but am up for anything.
