21 year old girl looking for accomodation Bologna from february

Hi, my name is Maria Saldi and I am a 21 year old girl studying Sociology in Belgium . I am coming to Bologna in the second semester. I am looking for a single room in the centre, not too far from Strada Magiore and not over 500 euros (expenses included). i am either looking for a room for myself or a flat that i can share with a friend that is coming to Bologna too. I am very sociable and love to have cosy evenings with my roommates. I also like to go to cultural activities and to go out at night. I am looking forward to my stay!
