18 year old looking for room in Rotterdam

Hello, I'm an 18 year old guy from Italy/Ecuador. I am going to my first year of university to pursue a bachelor in International Business in the Rotterdam Business School. I'm a social person. Parties are fun but I also enjoy staying at home at times and relaxing. Hobbies include both watching and playing football, going to the gym, cooking and many other things. I'm a quiet when I need to be and social when needed too. 

I just would like a room to stay in. It would be nice to have some people of my age but any is fine, really. I'm not very picky so just a nice place to stay, good company and I'm all set.
