Isabelle was fantastic... so helpful and communicative ahead of and during our visit. The location was perfect for us: close to Sacre Coeur, close to Gare du Nord, and half a block from a metro stop (Anvers). Very spacious and comfortable. Two of the bedrooms face the street and two bedrooms overlook an interior courtyard. Some street noise, of course... typical of any city. We would stay in Isabelle's lovely apartment again. Just one thing to note that we didn't see mentioned in any of the other reviews: the wooden floors are squeaky. Not a problem except in the middle of the night when trying to quietly walk down the hall to use the bathroom. More than once we ended up awake in the middle of the night despite our kids' best efforts to tiptoe silently to the bathroom. Everything else about our stay was perfect!
