Looking for a place to stay in Dortmund for WS 2017/2018

Starting to study in FH Dortmund this winter semester, and I'm looking for a place to stay.

I'm not too picky, almost anything is okay (see preferences below), but I would just prefer a place near a train station that's a tolerable commute away from the FH.

In general, I think I would be a neat flatmate with lots of stories and humble cooking skills (but great enthusiasm) to offer. I like to laugh. I don't like scary movies too much. I love music. I love food. I love being active, so if I suddenly find myself with a flatmate I can go jogging or go to the gym or throw disc with, that would be awesome.

Will be moving all the way from the Philippines, so really looking forward to learning more about German, Germany, Dortmund and meeting all sorts of people.
