21 year old girl, no pets, looking for accommodation in Hamburg

I'm a 21 year old girl from Nigeria.

I am a prospective Msc in Economics graduate student at the University of Hamburg come Winter 2015/2016 semester.

I don't have any pets, I am quiet and neat (sometimes), friendly, open minded and interested in meeting new people and trying out new things.

Type of accommodation could be anything from shared flats, student dorms, apartments as long as the total rent per month doesn't exceed €400 (I have a pretty small budget) anything below is galdly welcomed.

I am looking for something long term, but at least a minimum of 6months.

My roommate can be anyone {preferably female(s)}. Nice personalities are welcome, any race and age, degree of study. We can get to know each other better later.
