An absolutely fabulous location. The apartment is bright, modern and definitely spacious by Paris standards. Bed was comfortable, shower had great water pressure, and the kitchen was well-equipped if you'd like to cook at home. Wi-fi signal was fast and strong.
We travel to Paris quite often and were still impressed by the convenience the central location provided. You're steps from the Louvre and other great museums, Notre Dame, shopping in St. Germaine and close to two Metro lines. We love to walk and enjoyed heading out to various neighbourhoods on foot - the Marais, Opera, the Sorbonne/Pantheon - about 15 - 20 min, with lots to see en route. For Montmartre and Canal St. Martin, there's easy access by Metro.
Right below the apartment, you'll find an excellent selection of food shops, including an organic store and some great charcuterie and cheese at Cul de Cochon up the street (if energy is waning while you're walking, they sell paper cones of saucisson and cheese for 2 Euro). Be sure to enjoy wine and nibbles at Bar Etna just a few doors down from the apartment and great seafood at Fish la Boissonnerie just around the corner.
