The two main strengths of this apartment: (1) A phenomenal location half a block from the Rue du Faubourg Saint-Honoré and in easy walking distance of the Place de la Concorde and two metro stops. (2) The excellent communication (and follow-up) of the rental company, even on weekends and at odd hours.
Three minor weaknesses: (1) The kitchen lacked cooking basics, such as salt, pepper, or a little olive oil. (2) The worn (and partially torn) carpet in the building's staircase somewhat compromises the sense of arrival. (3) Contrary to details in the listing (at the time we booked), the pull-out sofa bed is located in the living room and not in one of the bedrooms. Note: The rental company recognized that error and provided a comfortable rollaway bed the next day.
Overall, I can recommend this apartment and Sweet Inn!
