looking for accomodation in Palermo

Hey, my name is Marta, I'm from Portugal and I'm going to Palermo for my erasmus exchange semester during my Master's Degree in the beginning of 2019. I'm looking for a room in a shared flat near the center of Palermo with a good connection to university. It must have a room with internet connection, a washing machine and heating. The maximum price is between 200 to 250 euro per month included all bills. It would be nice to live with roommates who are friendly.
