24 year old looking for a single flat in Vienna

I'm a bachelor in history who is looking for a single appartement in Vienna for a duration of 5 months, preferably from 15. September 2014 to 15. February 2015 or 1st March 2015. I'm also open to staying in a shared apartment if there is a nice group of colleagues looking for another person to ˝fill in˝. In my free time I practice judo which keeps me ocupied, but my main focus will be studies. All in all I'm a tidy guy who prefers order and peace. I'm also a sociable person who likes to have fun but sticks to agreed rules and duties.
