A small and excellent place to rent. Everything you need and as a base to do Paris it was good. Metro close and easy, flat was small (there was not much privacy!) but as a family that was not a problem. We managed with a family of five with children of 13, 11, and 9.
As with all places in Paris it was small, more of a studio. It had a curtain to separate the living area from the bedroom, rather than an independent room, and the mezzanine was really a 'bolt-on' affair.
But we loved it and explored all over Paris from here and even when stuck in for a wet morning with 5 of us, it was fine.
Contact and communications was excellent - very friendly and informative, and accommodating.
We would certainly use it again.
