Great place to stay. Isabelle, the owner, was quite helpful. The flat is cosy, clean, well-equipped. Fantastic neighbourhood (the 12th arrondissement), with lots of things to do, and great restaurants. Walking distance from the Bastille, Marais, Place des Vosges, Jardin des Plantes, Marché d'Aligre etc. I would definitely recommend. And I would have no problem at all in staying there again.
