I really enjoyed my stay. Everything is so clean and organized. They supply you with shampoo, conditioner, and body wash. Even a blow dryer, which is convenient if you're from America.
The area has so many options for food and it is so easy to get to all the landmarks. You can walk to almost everything or take one of the many metro stops. There are also some nice local treasures like gardens, fountains, shops, etc.
If you don't need a lot of space, this place is perfect. Stephan & Marina are very prompt with their responses and seem very knowledgeable of the area. They leave a booklet of recommendations, where to locate things in the apartment, and directions to popular landmarks. I would definitely return should I make another trip to Paris!
