I *highly* recommend staying here. Favorite parts of the apartment included the comfortable mattress, the big tub (it's perfect if you like a bath), lots of kitchen appliances for cooking, a cozy sitting area and even a washer/dryer.
Outside of the apartment itself, Kelly (the host) was absolutely great -- she had tons of local suggestions next to the (super centrally located - yet quiet!) apartment, a quick response time, and a binder full of all the apartment details you would ever need.
Can't wait to come back to Paris and stay here again.
