This is a gorgeous apartment and an opportunity to be in the heart of Paris, in a quintessential Parisian-styled apartment.
Firstly, it is very quiet, which is very rare for a center-of-city Airbnb. Because it is on the 5th floor, tucked at the end of a small street, there is very little street noise. We slept with the windows completely open and had no problem with sound.
The location is great. You have the Leige, Pigalle, Blanche metro stations all less than a 10 minute walk, and St Lazare just barely more than 10 minutes away. Plenty of boulangeries and patisseries close by as well as good restaurants and shops.
Like almost all apartments in Paris, there is no A/C, but we were there during the hottest heat wave in 15 years (close to 40 degrees each day) and found the apartment mostly comfortable. In normal hot weather it would have stayed very pleasant. Because it's at the top of the building, you get a lovely cross breeze when you open the windows.
Comfortable beds that were great for our family of 7 (we had two on the sofa bed).
All in all a great stay.
