The flat is absolutely wonderful and clean. Staying there gives you proper experience of a Parisian. The building is very authentic with long inner yard, narrow stairs and small doors. Great bed. A bath was a special treat for us. No problems with water, it's hot and the pressure is good. The location is superb, very well connected. It's full of life, plenty of places where to eat or have a drink, many bakeries around, but not too touristy at the same time. Jean Leon and Saskya are incredibly lovely and friendly people. Pity, we didn't get the chance to talk more. Probably next time :)
