23 year old guy, looking for accomodation for a periode of the second semester

I'm a Russian student studying Mathematics in France since 4 years. Rome is my second erasmus exchange. I m looking for an appartement or a room. Personally I prefer to live in the company and I like balanced people who know how to share the time between studies and parties. The last one is very important cause if I have roommates I would prefer them to become my friends.
