20 year old boy looking for accommodation in Paris for 4 months

I'm doing my Erasmus in Paris and I'm currently looking for an accommodation, if possible an apartment to share with other erasmus students. 

I consider myself someone who is really pro active and someone who likes adventures and doesnt like being home doing nothing. I am really looking forward to find Paris most coolest places while getting to know other Erasmus students that are in the same situation has me. 

While doing my Erasmus one of the things that I'm more looking forward is to travel around France and create life time memories.
