My husband and I spent a week in Paris this August. It was a very pleasant stay. This apartment is in an old building and has a lot of character, yet offers modern comfort. The apartment is relatively small, more like a studio, but very well equipped and organized. There was plenty of storage and closet space. The bed is very large (king?) and comfortable. Central AC helped a lot. The shower has a rain head and a separate handheld shower wand. Towel warmer is a nice touch. Kitchenette has everything you need, although we did not have to cook much. Also, washer (which functions as a dryer as well) worked great.
The location is superb! It is an easy walk to Notre Dame and to Louvre. The subway (Metro) station is very close. A grocery store is literally around the corner. The street is full of restaurants, bars, bakeries and an ice cream parlor.
When we had questions the Habitat Parisien responded right away, which was really amazing!
If we will travel to Paris again, just the two of us, we would definitely try to book this place.
