21 year old girl looking for accommodation in Amsterdam to do Digital Media Marketing internship

My name is Martine. I'm a fun and creative girl who's got a great internship in Amsterdam doing my dream job. I'm looking for a single bedroom in a shared house or a studio apartment that's not too expensive. I need somewhere to live from the beginning of June until the middle of September. My internship is in the West part of the city, so ideally somewhere close, or in the center of the city so I can easily get the tram there. I'm a tidy and quiet person who likes to watch Youtube and write my blog.
