HHU PhD student looking for a WG or an apartment (Max. 650 Euro warm)

Hi,
I am Gürbüz. I am 28 years old and a PhD student at Heinrich Heine University studying computational biochemistry. I mostly enjoy reading (mostly history, pop-science), listening music, watching documentaries and football. I like to keep my living area clean and I have some experience living in a flatshare during my master’s.
I have a relaxed personality and would be happy to join my roommates in the evenings for cooking/drinking beer/going to a cafe/just chatting. I also like to retreat to my room and relax myself. Mutual respect and privacy is important so everything can, nothing must.
My German is very limited as I have just started learning. I am looking forward to learn the language and start speaking with my roommates as soon as possible.
I don’t smoke and I don’t have any pets.
I am looking for a long accommodation, at least for a year, preferably longer than that.
You can reach me here by sending a message.
Best regards,
Gürbüz
