Looking for one-roomed apartment

I am a PhD student in mathematics at Iv. Javakhishvili Tbilisi State University. I am going to visit in Göttingen (University of Göttingen) for one year within Georgian-German scholarship. I am looking for an one-roomed furnished apartment. If a roommate is female it is possible to share the room. I am sociable and love interacting with people. I like getting up early, cleaning the room and also cooking. I enjoy walking, watching good films (such as: documentary, based on the true story, adventures, drama, animated, etc.). I prefer to be in cozy atmosphere. I am non-smoker person and I would like if my roommate is also non-smoker. I keen on travelling, going sightseeing, meeting friends, shopping, etc.
