This is a great apartment for a stay in Paris! It is on a quiet street in an otherwise busy area. It has a very central location, and a few minutes walk from the RER/metro station with direct trains to/from CDG/Orly airports. The beautiful Jardin du Luxembourg is a few minutes walk away, as are countless cafes, bistros, restaurants, an epicerie, groceries, etc.
The apartment is in a lovely small building, and was spacious enough for us and our two teens. There are a double set of doors in the entry, and the building feels very secure. The furniture is comfortable and stylish and there was ample closet space to hang/store clothes. It is on the 2nd floor; there is a small elevator, but it would probably best be used only for luggage (or a very narrow person). There are two floor-to-ceiling windows with a small balcony, with a view onto the street. The kitchen was well-equipped and clean. We felt very at home here and I would highly recommend this apartment!
