24 year old man, looking for accommodation in Vienna

I'm a 24 year old masters studenf from Estonia, studying chemistry at the university of Tartu. I'm coming to Vienna in the middle of september 2020 to participate in the Erasmus winter semester at the University of Natural Resources and Life Scieneces Vienna and I'm looking for a room in a shared apartment. My stay would be about 6 months, the departure date back to Estonia I haven't decided yet, but it would be sometimes in the first two weeks of febuary 2021. 

I'm looking for a room in a shared apartment,  preferably it would 15 m2 or bigger but if it's a nice smaller room then I would also be interested, fully furnitured (bed, desk, closet). If the apartment has a balcony and/or a shared living space then it would be a great bonus. 

About me: I'm a non-smoker, tidy and like to cook, also athletic (running, cycling, rowing, hiking, snowboarding etc). When going out I like to have a beer or two. I also speak german.
