This is the ONLY place to stay when visiting Paris. Susan & Vincent's place has the best location that we've ever stayed at with easy access to nearly all of the main sites in the center of Paris. Easily walkable but if needed - closely located to three different subway (Metro) stops within minutes.
We enjoyed the convenience of the Carrefour market just across the street for smaller food items, but about a five minute walk to the Monoprix where there is a proper, large supermarket for just anything you might want to prepare/eat.
Susan was most helpful in getting us settled in the flat and making a quick explanation of the area.
Location is everything when considering property and this apartment is certainly fulfilling of that demand.
