Dalia is looking for: A Room / Apartment / Rental Property / Studio / HouseBoat in Amsterdam

Goedemorgen! I am sorry, but the rest of this message will be in English, my Dutch is not that good yet.

I am a 25 year old Student from Germany, who will be studying at the University of Amsterdam this September. I plan on moving in with either an established house of students, or into a flat with one or two other female Masters students that I know already.
As such I am looking for either:
A single room or 2 bedrooms or 3 bedrooms.
As Masters students I believe we are probably more reliable than younger and first time students.
Thank you!
