21 years old boy looking for a studio or shared room in Lyon from end of August until end of December

I am a business student in Lithuania and I will be participating in the Erasmus+ program for a semester in Lyon at the Catholic University of Lyon. I want to find accommodation for a reasonable price and I am willing to share a room with another person. I am a quiet person, I like reading and walking around the city, I don't smoke (but I don't mind if the other person smokes), and I am up for having a good time partying or just going out.
