Looking for a place to live in Aachen (student, worker)

I'm Lucas, 20 years old, brazilian, Computer Science student. I am going to Aachen in December to work for a Software Development company. I'm very easygoing and open-minded, clean, silent and respectful. I am searching for a place to stay.
In my free time I love to spend time with friends or my flatmates, we cook, drink, go out and have lots of fun together, so sociability wouldn't be a problem. I also love watching tv shows, movies and walking around to see the city. I try to travel as much as I can and learn new languages.
Please contact me if you're interested and we can talk more about it.
