20ish year olds (4) searching for a flat or separate rooms for a year abroad (2 sept-20 june)

We are looking for a place to stay the whole year in Lille. We are erasmus students and we will study at Lille 3. I don't mind getting a place alone with some strangers that want an erasmus with them, actually I prefere that but if it's possible to stay the four of us together much better. We are spanish, from, I know English, French, Spanish, and a tiny bit of Deutsch and Romanian.
