23 year old boy looking for accomodation in Krakow with foreign students

I'm a 23 year old italian student. Undergratueted in Political science i'm currently studying politics for international cooperation at the UCSC in Milan. It will be my first erasmus's experience and my first time in Poland. I will be in Krakow from February to June and i will study at the Jagiellonian university.  I would like to find a private accomodation to share with other students. I prefer to find foreign roomates in order to improve my english knowldege. I'm looking for accomodation in the city centre, maximum 15 minutes walking distance to Jagiellonian university.
