Seeking housing in Aachen (March 1 2020 - July 31 2020)

I am a 22 year old Belgian Chemistry student, currently doing his final master year at the University of Antwerp. I'd like to perform my Master's thesis at RWTH Aachen (Institute for Organic Chemistry), but for this, I am looking for housing.

I take my studies seriously, and I will be in Aachen primarily at the university. It is not that I am not open to meet and interact with other people, but my main goal is to write my thesis. My free time is at the moment mostly spent watching a movie or series. In addition, I have a close group of friends (with whom I manage to meet not often enough), which I met during my years at highschool, performing in the theatre group of the school.
