Beautiful, comfortable apartment in a great location. Benoit's apartment is on the first floor but completely secure and quiet in it's light and plant filled courtyard behind a massive wooden door. (You can hear the metro. Bring earplugs or a noise-cancelling app.) Anything you could want or need is a short walk away. We were surprised by the functionality and beauty of this apartment. Very thoughtfully put together. We were very happily surprised by the comfortable bed - typically one of my least favorite things about travelling. Great bed. Nice details -lighting, linens, desk, colors. We enjoyed a restful, restorative week in a city we love. We highly recommend 4 rue de Babylone and hope to return soon.
