I spent a lovely 3 weeks at Anne-Marie's apartment. As other guests have mentioned, the apartment is very quiet; yet , when you go outside you are in the center of a bustling Paris. Metro line 1 is just a few steps away, and can get you anywhere. Local markets are a short walk away: Carrefour, Monop', and Franprix. You're in the midst of the shopping area on Rue de Rivoli, and not far from the Rive gauche and the St. German des Pres area.
A wonderful location!
