I would recommend Èlise and Sébastien's place. Their approach is very professional, check in was easy, and the apartment is spacious for Paris. The two bedrooms in the back were quiet, the bedroom at the front had some noice from the street. Location is great: good facilities (cafes, restaurants, grocery shops) in the neighbourhood, metro with 5 min walk and it's only 15-20min walk to the Louvre.
