Franck was a pleasure to work with and was exceptional in his responsiveness both before and during the visit. The location in Le Marais is ideal, both because there are dozens of excellent cafes and restaurants nearby in this bustling neighborhood, but also because many sites (Pompidou Center, Picasso Museum, Notre-Dame, many others) are within easy walking distance. A metro stop is just around the corner, and shopping, both affordable and high-end, is plentiful. You are literally five minutes from the Seine!
We enjoyed the apartment and found it spacious for our needs, with a nicely-equipped kitchenette, a good-sized bedroom with closet, a generous living room, and a great shower. So it felt more like a home than a hotel room would, which enhanced our stay in Paris and allowed us to relax when we were tired from site seeing. There are three flights of steps to climb, but we're in our early 60s and this wasn't an issue for us. There is no question that the building is old, but for us this patina only added charm to our experience. My wife and I recommend Franck's place to those who are looking for an authentic Paris experience.
