25 year old Finnish student looking for room/studio for May-September

I'm a Finnish-Swedish student who will do an internship in Amsterdam during May-September. I'm 25 years old and responsible and independent. I am used to living with other people since I've lived in different roommate situations before. I'm social, outgoing and positive. I like reading, blogging, writing, partying occasionally and a good laugh with friends.

I'm looking for a room in a flat or a studio in the city center area or an area that is easily accessible from the center.
