23 years old girl looking for a flat share in Paris

I am a 23 year old Textile Designer. I am coming to work in Paris for a 6 month design internship. I am looking to share a flat with like-minded individuals who share similar interests. I would like a sociable living environment where we could eat dinner together sometimes and go out together at the weekends. I enjoy a nice glass of wine with dinner and eating well. At the weekends I would like to explore Paris and see exhibitions. I'm looking for a reasonably priced apartment - it would be nice to live in a 2/ 3 bed apartment and I don't mind which gender. English speaking would be preferable but I am keen to learn French - so anyone who would be willing to practice together would be great! I am going to be working in the area of La Défense (Pont de Neuilly/ Pont de Levallois), Paris so would ideally be looking for something on Line 1 or 3. I will be in Paris from the 1st to the 4th of September so hoping to secure a flat during my stay.
