Definitely the best location is all of Paris. Two minute walk to the rer b metro which takes you directly to airport. Five minute walk from notre dame and ten minute walk to cafe de flore. Quiet and safe area. It’s my favorite place to stay. Building is one of the oldest in Paris with amazing history. Victor Hugo used to dine there when it was a restaurant. Phoenice is so kind. She answered quickly and she gave us tips on metro tickets and other things. Definitely worth staying here as you can make your own breakfast. There is market right across house if you want to buy dinners or snacks there too.
