20 Year Old Looking For One Room Flat (Aachen-Mitte)

I am a very friendly person who enjoys making new friends, but I also need my space and a quiet, clean and orderly place to live in. I come from Brazil, lived in the United States for a few years, and am now living in Germany nearly finishing a language course to re-enroll in the University for a Biology major.
I’m looking for a flat with a kitchen, partly furnished, with a washing machine, internet, and preferable an all-inclusive rent price in or next to the center of the city. End of March/beginning of April time room would be great. Please don’t hesitate to send me a message or text me on whatsapp :)
