Software Engineer looking for a room in a flat share

I'm a 24 year old guy from Tunisia and I'm just about to finish my studies in a Tunisian university. I'm a pretty laid back guy and I like to think of myself as an open minded and accepting individual. I don't find trouble getting along with most people but I respect people's boundaries. For hobbies I enjoy video games and reading when indoors but I also enjoying bouldering and playing some sports every now and then. And then of course there's also going for a few beers with friends every now and then to unwind and catch up

I actually have been in Aachen for the past 4 months for a Software engineering internship and I got lucky enough to land a job with the company I interned for. So I'm coming back to Aachen again in November for the Software Engineering position once I finish getting my degree This September. So I'm looking for a room in a flat share, or a 1 room studio, preferably for long term.
