A one-room apartment or a room with private bathroom for student life

I am Sina, and I am looking for a nice quiet one-room apartment or a room with a private bathroom. As I will start my master's studies at TUM on October first after completing my bachelor's degree as one of the best students in my class at the best university in my country. I am a clean focused person and I will be at the property mostly at night. I will bring my total first-year living costs (including rent) from my home country in cash as an obligation from the German embassy. Proof could be presented. would be happy if we could discuss the details and payment method. You could contact me via my e-mail or text me on Whatsapp (the mobile number in the ad). We also could set up a video call.
