Looking for a 1/1.5+ bedroom apartment with attached kitchen and bath

I am Dr. Rajendra Giri, originally from India. I am working here at the Kiel University as a research scientist. As I am getting married in next December I am looking for a family suitable apartment at least up to end of next year or more. Also I am completing 2 years, the maximum one is allowed to stay, in the Uni guest house (my current apartment). So, I have to move out from there anyway by this December. However, I am ready to move out before that. But I have to inform the Uni office 1 month beforehand.
However, I am looking for at least 1 bedroom, 1 small drawing room with attached/separate personal kitchen and bath. My budget is 550 Euro incl. warm cost and additional costs , but is negotiable.
