22 years old american girl looking for accommodation in Paris

Hi my name is Denisse Zamora im an american girl from LA looking for a room to rent in Paris! Im 22 years old, an animal lover, very down to earth and positive person that loves to interact and meet new people! My plans are to stay in Paris for new years eve, it would be such a great life experience. I arrive the 11 of December. I might decide to stay a little longer that depends if its ok with the owner. I know Paris has 20 areas.. I was trying to find something on or near the 8th But if not thats also fine! I'm keeping my options open!
