20 years old, Erasmus Student. I am looking for home

Hi! I am Gizem and I'm 20 years old. I live in Turkey. I am Erasmus Student and I'm going to study at Hannover. Therefore I'm looking for a place. 

I'm looking for a room of 10-15 square meters. The room is furnished. I mean, there must be a bed, a wardrobe and a desk. I would prefer not to have a stuffy or dark room, so there should be a few windows. These are all I want. 

I speak intermediate English and very little German. I am respectful, orderly and cheerful. I love to watch movies, eat vegetables and visit historical places. If there is a landlord carrying at least two of the three features mentioned in the previous sentence, I'm sure I can be a good roommate!
