A cameroonian dude, looking for accommodation in potsdam. Preparing for my masters

I'm a well traveled cameroonian citizen,  currently living in Bahrain. I work here as a bartender. Lived in China  Japan, Singapore before relocating to Bahrain.  Now getting ready for my masters program in Berlin. 

I'm looking for a simple room, (studio) with a bathroom and a kitchen. I don't mind a room in an apartment. I'm a sanitation freak, super organized and respectful. I don't mind anybody's business cus it ain't mine. I might prefer other nationalities or ethnicities maybe South Americans(latinos) Europeans, Muslims etc.
