I stayed in this beautiful/ stylish apartment with my 14-year-old daughter for 4 nights for our mother-daughter Paris Trip. We both absolutely loved it. The apartment is within 5-minute walking distance of 3 different metro stations with different lines, one of which, the Breguet–Sabin is a direct line from the Gare du Nord (only 6 stops), so very useful for us as we used Eurostar. The owners were kind and very helpful with our check-in and check-out, and always within quick communication. The apartment itself is clean, and just as the other reviewers have said, very quiet. It's on the top floor and there are no windows looking into the apartment, and we felt safe there, as you need to go through 2 doors to get into the courtyard.
