Single/Double sharing room for female indian student

I am a master's student at TU Braunschweig, currently pursuing data science, and I am looking for accommodation. I would prefer a single sharing room or at most Double sharing with personal bed. I am an easy-going person who values and respects boundaries and prefers to spend most of my time in my own space. Ideally, I would like to share accommodation with calm, like-minded students who also respect personal boundaries. I am looking for a place with basic amenities to ensure a comfortable living experience. I do not smoke and would prefer to avoid flatmates who smoke indoors. Having a peaceful and considerate environment is important to me as I focus on my studies and personal projects. If this sounds like a good fit, I would be happy to connect!
