20 year old girl looking for room in Paris

Hi, I'm Stiene, a 20 year old student from Belgium, and I'm looking for a room in Paris. I will be staying there from September - January for Erasmus. I study French and English literature and linguistics in Leuven, and will be attending Paris X in Nanterre from September for one semester. I'm looking for a room (preferably a room in a shared flat) close to St-Lazare, so 8th or 9th (17th or 18th too if it's close enough) arrondissement would be perfect - or something close to a RER A stop. I'm a very sociable person, I speak Dutch, English and French (though not perfectly, I'm coming to Paris to optimize my skills - so a French-speaking family/roommate would be great), I like books, art, movies, music, theater and musicals. Feel free to send me a message if this ad applies to you! See you soon.
