I need a room( shared apartment) to rent in an area close to RWTH Aachen University

I am a God fearing 27 year old man from Ghana who is looking forward to studying MSc Applied Geosciences at RWTH Aachen University. I am easy to hang around with and very friendly. I do not smoke and I do not like making noise either. Safety is part of me hence I obey safety rules where ever I go. My adage has always been do unto others what you want others to do you. I am yet to work in Germany but I look forward to applying for job when I arrive. I would like to rent a shared apartment or single room which does not cost more than 250euros and is not that far from RWTH Aachen University
