21 year old gril looking for accomodation in Rio de Janeiro

Hey ! I'm Lola, French Student in Economics and Political Science, coming to Rio in August for a four months internship and looking for a room in an appartment or a house with roomates. I'd prefer to live in Santa Teresa, Lapa, Catete or Gloria, but Copacabana or Ipanema would work for me too :). I can speak French, English, Spanish and a little of Portuguese. I'd say that I can be a quiet, nice and well organized roomate. I also like to go out (to the beach, museums, theater, and of course to party!). I really love travelling and discovering new cultures and new stuff ! And I can cook !
