Exchange student looking for a flat

My name is Gustavo I have 23 years and I am an exchange student from Brazil. Currently I am enrolled in the Mechanical Engineering course but have a background in computer engineering from Brazil and I am working in a company that makes Smart Glasses aplications here in Aachen.
My main hobbies are playing games and cooking, with a bit of games creation too. Most of the time I am not home because of work but I really want a cozy place where I can just relax and cook a good meal.
I'll be staying in Aachen until August/2019.
Some place near the city center or the west part of the city would be better, but anywhere with reachable bus stations and facilities like markets and restaurants are also good.
