22 year old master's student looking for a room in Ljubljana during Erasmus exchange

I'm Laura, educational science student from Finland coming to Ljubljana from September 2017 to February 2018 to study social sciences. I'm looking for a place to stay during that time - preferably a single room in a shared apartment. I would appreciate a location at the center of Ljubljana or close to the faculty of social sciences. I am sociable and would also appreciate hanging out and traveling with my flatmates but not looking for the craziest party apartment. My ideal flatmates would be (master's?) students who are easy to live with.
