I am a 21 years old girl from Hong Kong and I am looking for accommodation in Lyon.

I am Jessica and I am going for an exchange from this year September to next year January in Lyon 2. I am majoring in language and I am always willing to meet new friends. I am currently looking for accommodation in Lyon 2. I am looking for a single room to stay for about 5 months. I am okay with shared kitchen and toilet as long as the toilet is clean. My biggest concern would be security and transportation. It is because Lyon 2 has two campuses which are distanced with each other so I hope the recommendation could be public transport accessible.
