I've stayed in a lot of Air BnBs over the years, and Mathieu and Alis's place ranks in my top three best stays. The location is incredible for so many reasons. You walk outside the building, and you're surrounded by everything you would need. A bakery, butcher shop, cheese shop, fruit vendor, seafood vendor, cafes, restaurants...gelateria. It's awesome and so very French. Once you're off the street and inside the courtyard to the building, it's quiet and quaint. The apartment is clean, has lots of natural light, a well stocked kitchen (as far as cooking utensils, pots, pans, etc.), and a spacious shower with great water pressure. It's perfect for two people. Anymore than that, and it would start to become a bit tight, but it still may be worth it for the reasons above. Mathieu was very quick to respond to any question I had and provided some great restaurant suggestions when I asked (I Grappoli, an Italian trattoria within a minute from the apartment door step is fantastic). Lastly, the local Metro station, Denfert-Rochereau, where you can catch a train directly to and from Charles De Gaulle Airport, is a three or four minute walk away from the apartment. Can't recommend this place highly enough!
