22 year old student looking for accomodation in Helsinki

I am a 22 year old Masters student from Paris Saclay University. I will be spending  4 months in Helsinki during which I will be working as an trainee in the astrophysics division of the University of Helsinki. 

I am looking for a shared flat with other students of Helsinki uni to immerse myself in the finnish way of life, and that includes learning a bit of the language !

My interests include reading about the philosophy  and history of science, I am a huge Tolkien nerd and as such I can bring a tavern-like vibe if a pen and paper role playing game ! Other than these "camaraderie surges" I am a quiet, easy going person!

I am looking forward to this trip to the land of a thousand lakes (or 200 000 ish),
