French trainee looking for a room for three months in Rotterdam

I'm a french student in Rotterdam for an internship until the middle of July. In France, I'm in my second year of Business Administration Studies. Easy going, I've already experienced flat and room sharing for two years while studying in France and in Lithuania. Passionate about travel I've been living in Lithuania for 5 months and I traveled in many European countries. Also passionate about sports, I'm a daily runner, swimmer or bike rider. To tell you a bit more about I'd be as a flatmate I like to chill watching movies, TV series or documentaries in the evening and I enjoy to go out and party on the week-end.
