19 year old young Man, looking for accommodation in Bremen

I'm a young chill guy. I am taking a german course near the Main Station from Bremen to pass the TestDaF exam. So i will probably stay relax studying and focusing in my test. The Hochschule Bremen has already accepted, so after i pass my exam in the 5th of november, I ll go back to my homecountry , and return on March for my first semester. After that i ll stay in Bremen undefinately until I finish my study. I speak 3 languages : Spanish, English and German. I would like a roomate maybe around my age.
