IT student searching accomodation for residence permit

Hi! My name is Ilyes and I'm searching for a shared/single room in dorm or wg. I already applied everywhere i can, as my residence permit application deadline is early September. My  budget is 300-450preferably, absolutely max 500 (with all costs included).

i don't smoke and i have no pets, also most of the time i will spend probably in uni. If u searching for a silent introverted room/flatmate, then u found him! 

I'm searching a place from 1.2.2027, for the first semester of my studies (which ends in june/july). 

Only Vienna with good connection to U3, but as my budget is as it is, I'm open basically to anywhere in Vienna.
