23 years old erasmus students looking for accomodation in Vienna for 3 months

We are two erasmus students and would like to share an appartment with two bedrooms and a shared kitchen, living room and bathroom. We have no problem having other roommates. But the important thing is that we want to have separated rooms. In case that you can find one room in an appartment (which means that is for one of us) its ok then we are going to search for one more. We prefer an accomodation nearby Michaelerplatz and the Department of Neurobiology  where we are going to work is located in Althanstraße 14, 1090 Wien, Austria. 

Thank you for everything.
