Looking for a single room in a shared apartment

Hello,
my name is Angela, I’m 22 and I’m from Italy. I will study at the RWTH University this semester, as an Erasmus student, but I still haven’t an accommodation.
I’m looking for a single furnished room in a shared apartment starting from the 1st of October, until the end of February. Alternatively, I’m also looking for an entire apartment with more bedrooms to share with other students.
I’ve been living alone since my first year of university, four years ago, therefore I am reliable, and I like living in a clean and tidy place. I’m a very extroverted girl and I can’t wait to meet new people and enjoy this experience.
Thank you in advance for your help!
