23 year old female student, looking for a room in Paris

I'm a political sciences student from Finland, who will be studying at Sciences Po this spring. I enjoy both city life and nature, good food, conversations and beer. I'm always looking for new experiences, which is probably why this will be the fourth time I live abroad during the past few years. I'm looking forward to share a flat not just to reduce costs but also because I want my exchange experience to be social. 

I'm looking for a shared apartment or room in central Paris or roommate(s) to look for an apartment together.
