I stayed in Frantz's apartment with my Fiancé, & 10 year old daughter. We had a lovely time within the quirky and delightfull apartment, and were able to traverse Paris with ease from its location.
There are no shortage of restraunts, shops, & café's nearby to enjoy, as well as many sights and view points right outside the door.
I fully recommend a stay in Frantz's apartment for couples and small families, and would stay again should we return to Paris.
