Need a room in shared-flat in urgent

I am a new girl who will study in Rostock, is seeking a room in the shared-flat or shared-apartment(only female resident). The preferred districts of living place are Kröpeliner Tor Vorstadt (KTV),Stadtmitte and Steintor-Vorstadt. It is better to be close to city center and main station.I wish the room is furnished with at least a bed, a studying desk, and a small wardrobe. I am a girl who like to keep living place clean,welled-organized and less-noise creator:), not smoking.I hope my prospective flat-mate would have similar hobbies as I do (as describe above). There would be up to 3 persons in the shared-flat, I don't mind to share kitchen and bathroom. The price for a room (min size 12m2)is maximum of 350 euro/month.I would like to start with renting for 3 months first (1st December 2013-28th Feb 2014). Looking forward to hearing from you,please help me out with accommodation. Thank you very much!
