21 year old Psychology (Erasmus) student looking for roommates in Pisa

I would like to stay with people same age as me not so young and not so old, I would like to be with people who I can hang out with, I'm looking for a cheaper place. I'm a private person and I study a lot, somebody who respects that and who can adjust would be great. Besides studying i'm an easygoing, friendly, kind person who really likes to meet new people and make new friends, i'm talkative around right people and I would like to be with people who are interested in exploring Pisa together with me.
