We enjoyed our stay and loved the neighborhood. The flat has a great location -- a one-minute walk to a corner boulangerie, a five-minute walk to the Metro, and a seven-minute walk to Musee Rodin. The flat is in the 7th Arrondissement, close to the 6th. There are bistros, chocolate stores, dessert stores, and grocery stores a few minutes away. It is a quintessential upper class Parisian neighborhood. The owner was helpful, gracious, and quick to respond. The flat has lots of windows and light. It is simply but comfortably furnished.
Please note that the flat is on the seventh floor of a building. There is an elevator but it is very narrow, designed to fit in the building's stairwell. At most, two people can fit in the elevator at one time (or one person with luggage). A large person might not be able to use the elevator and going up and down the stairs a few times a day would be a hassle.
