Looking for a room in a shared apartment or a studio type apartment

I'm an international student at Hamburg University. I was successfully selected for 1-year qualifying fellowship for an MA programme. During my stay in Hamburg, my main focus would be on my studies. And during my free time, I would like to discover the city and get to know the culture. I'm a friendly and kind-hearted person. And I'm also a calm and a very clean person. I don't drink or smoke. I speak different languages including German. During my stay, I would also like to improve my German speaking skills and create different types of networking connections. I'm looking for a clean and good place, either a room in a shared apartment or a studio type apartment.
