Ruhiger und Sauberer Mieter sucht 1-Zimmerwohnung in Berlin ab dem 20. April - Quiet and Clean Tenant Seeking 1Room-flat in Berlin from April 20th

Hello I'm Anas, 23 from Tunisia, I speak Arabic, French and English. I'm coming to Berlin in April for a 5 months internship there. It's my first time coming there, I have friends and many university alumni there. My source of income will be my salary as the internship is the same as work.
My daily routine will be going to work all day then maybe going for a drink or discovering the city then coming back home have dinner, maybe a chat or something I don't really mind that.
I am a calm, respectful and tidy person who values a clean living environment.
I do smoke a little (2-5 cigarettes a day), but I am mindful of others and willing to discuss if this causes any problem. I am looking for a quiet and relaxed living environment where I can focus on my work and enjoy the company of friendly and like-minded people.
I would be happy to provide more information about myself and answer any questions you may have.
Thank you for considering my request.
