22 year old medicine student looking for residence in Vienna for the winter semester

I'd like a room with private bathroom (or share it with 1 person), the kitchen is not a problem if it's shared, in the centre of Vienna, maximum 20 mins by means of transport to the General Hospital of Vienna. I prefer dorms with music room (piano included). I'd like th room to be single and not shared, too. I study medicine in Greece, i am a big fan of classical music and play the piano and really exited for the life in Vienna!
