Three of us stayed in this apartment for 5 nights. The neighborhood could not be better. There are plenty of shops and restaurants around and you are very close to the center of Paris; we didn't even take the metro!
Marion was a fantastic host from start to finish. She responded promptly, answered all our questions, worked around our arrival and departure schedule, and even gave us some tips on places to check out.
Americans note that the apartment is small; smaller than the pictures imply. Once we settled in it was very comfortable, and the view from the bedroom of the rooftops was delightful.
