1 Room flat required near RWTH

I am a PhD student from India studying Nanoscience. I am visiting RWTH for 6 months internship and would need accomodation near RWTH. My duration of stay is from 01/02/2021 to 31/07/2021. I need accomodation for this period (duration of accomodation can be discussed further). I would prefer a furnished flat so that I donot have to carry too much stuff from my home country. This is my third trip to Europe and I would love to explore the culture here apart from my research work at RWTH. I would also like to learn German. Presently I am fluent in English and Hindi.
I am a quite and friendly person. Also, I like to keep my surroundings neat and tidy. I donot smoke. In my free time I like to listen light music and read. I also like travelling to new place and playing badminton. Hoping to make some great friend in Germany!
