25 italian guy looking for roommate in Paris 3 or 11

Hi, I'm looking for a guy who'd like to share a studio around 3rd or 11th ARR. 

The kinds of studio I'm referring to are these:

I've not chose one of them yet because I prefer before find a roommate with exigences near of mine and than decide together the right place where to live. My idea is to spend 500 euros each one.

Living together in a studio it's not easy becouse of its smallness. So I'd like to describe my character.

I'm a guy with interests like running, music, going out, but I study engineering so I need my time to study and I'd like a tidy roommate. I'd prefer also a not italian guy to exercise with other langauages and know other kind of culture.

I hope to find someone early.

Bye!
