I'm chiara, 22 italian, and i'm looking for a single room in wien

I'll attend the first semester in the TU university, i'm studying architecture and next year will be my last year of study. I'm searching  a  single room near karlsplatz if possible, I would like to live with other students (male or female is the same). I'm coming in september (after the 15th) and i will return in italy in february. I need a room with a bad, a wordrobe , table and chair. I love animals, going out and sports.
