25 year old student looking for accommodation in Amsterdam

I am mainly focused on my studies. When I'm not studying, I enjoy eating, reading and writing, and a movie every now and then. I'm looking for roommates who are clean, friendly and equally focused. My sister occassionally visits so she's a feature in my life. I also have 1 long long distance family call a week which might be irritating to some, but it's the only family time I get so bear with me.
