24 year old boy, looking for accommodation in Rotterdam

I will study piano master at Codarts University for the Arts. I am master student at İstanbul Technical University (İTÜ) and I will come to Rotterdam via Erasmus. I am clean and open-minded person, I like to travel and study music. I like to also go to a concert, play a gig, or do something about music. I am looking for a room, dorm or flat to accommodate. I hope I can find a dorm because I want to live in an international environment. But it is OK if I can find a room what I want.
