Ana, 20 years old girl, looking for accommodation in Dusselorf for an Erasmus experience

Hi everybody! I am Ana 20 years old,  and I'm looking for accommodation in Dusselorf to October from March, to stay in Erasmus here. 

I am studying advertising and tourism in the university of Cadiz,  Spain, and I am going to study one semester in Heinrich-Heine University. 

I am looking an apartment or a room to share with other students

I want to learn German and improve my English.  Also I want to discover new place and travel a lot. 

All kinds of suggest about accommodations or something in Dusselorf are being welcomed. 

Thanks for all.
