Engineering student searching for one room apartment

I am an Industrial engineering student that is coming to Aachen for exchange studies from Sweden for the winter semester. Therefore, I am searching for accommodation from 1st of October to the end of mars (2022). The accommodation type doesn't matter a lot, but preferably an one room apartment. Shared apartment works also well. I am also quite flexible with location of accommodation if there is good communication with RWTH.

A little bit short about myself: I am 22 years old guy who is calm, thoughtful and social. I also care about the environment that I am living in, in addition, I am a non-smoker. My financial status is good. In my leisure time, I like to cook different dishes, hike in nature, and sail when there is such a possibility. Today I have limited German language knowledge, but I am really excited to learn more during my stay at Aachen.
