21 year old girl looking for a room in Firenze

Hi, I'm looking for a single room in a flat or house to rent starting as soon as possible. Closer to the center would be ideal. I'm a 21-year old American girl studying here in Florence at the Accademia di Belle Arti. I would love to especially live with other students or young people in a friendly, multicultural environment, and would love to be able to practice my Italian as well. Fun or calm atmospheres are both appealing. I'm very clean and I love to cook, I'm quiet but friendly. I'm not picky as to the size of the room or most facilities but kitchen use is definitely needed.
