21 year old girl, looking for female roommates near the University of Zaragoza

I'm a 21-year-old girl from the U.S. and studying at the University of Zaragoza for the fall 2017 semester. I keep things tidy and am quiet! I want to travel around Zaragoza and Spain while I'm there and to speak Spanish as much as possible. I love going out exploring, drinking coffee, and playing and listening to music.  

Looking for female roommate(s) preferably, and looking for a fully furnished, clean flat near the university (ideally within walking distance). I'll be staying from September to the end of December, but am willing to sign a lease until January or February if that is what is available.
