23 years old medicine student looking for a single room in shared accommodation in Palermo

My name is Natalia and I'm a student from Poland who's going to carry out an internship in Palermo during the upcoming summer vacation (July & August). I am looking for a single room in shared flat near the University or the city center (neighbourhood doesn't need to be quiet at all, but there must be a good Internet connection :) ). I prefer staying with other students of any nationalities.  I don't smoke and I don't have a pet.
