Sstecken, 42

I'll be working as a research assistant in the psychology department. I require a quite and clean atmosphere during the week, but a place I can have a few friends over during the weekend. I'm a fairly reclusive individual, so I shouldn't have a problem getting along with you; however I've been in a bad situation in the past and require a mature and responsible roommate that knows how to take responsibility. I'm looking for a place near a bus stop to campus or within biking or walking distance
