flatshare house

I am a 26-year-old master's student from Bangladesh, currently enrolled in the Biology program at Karlsruhe Institute of Technology (KIT). I am seeking a flat-share room in the city, available from March 1st, with a shared kitchen and toilet. I do not smoke or drink, and I would prefer to live with other students or full-time professionals. Along with my stay, I would need all necessary documents for city registration and the activation of my bank account.
Being new to the city, I am looking for a peaceful, clean, and friendly living environment that provides a comfortable atmosphere for both studying and working. As I am a responsible and quiet person, I am hoping to find a respectful and understanding flat-share arrangement. If you have a suitable room, I would be grateful to hear from you and discuss further details. Thank you!
