21 year old Polish student looking for a single room to rent in Pisa

Hi everyone!
I'm Zuzanna - 21-year-old Polish girl looking for flatmates in Pisa. I will study Applied Linguistics as an Erasmus student for one or two semesters. I speak English fluently and I would like to improve my Italian. I know also German..but I haven't used it for some years and now it's almost forgotten ;) 
I am a normal, friendly and sociable girl - I'd like to meet new people, make a lot of friends, visit places at weekends, go out in the evenings when I don't have to study that much. I won't cause any trouble as a flatmate - I respect other people's privacy, I don't have any disturbing habits, I prefer to keep things in order. I just want to have fun, benefit from the Erasmus programme and leave Pisa with a wonderful once-in-a-lifetime experience.
What I am basically looking for is a single room in an apartment preferably close to the city centre. I am arriving in Pisa on 25th of September. I could spend max. 350e on accomodation - all costs included. I would like to have wi-fi connection and other "useful" facilities.
Let me know if you think I could become your flatmate ;)
