We had a great stay in Joanna's Paris apartment. Centrally located near Chatelet Les Halles and Etienne Marcel metro stops, among others. Easy walk to the Louvre, Sainte Chappelle, and much more. Groceries and many shops and restaurants just outside the door. Yes there are four flights of stairs, but you need the exercise. And be aware there is only one toilet/WC, which was described in the listing, but I hadn't really read closely enough. Bonus: for a central Paris location, the apartment was surprisingly quiet. Would definitely return.
