We had a super great time at this place during our 12 days stay in Paris (Aug'21).
The apartment is beautiful and feels like a nice place to be at, nicely decorated, it has plenty of sunlight during daytime and for what is worth, located in Le Marais on a major street, 300 meters from Notre Dame, makes it a perfect to stay while in Paris:
Location was key for having the best experience in the city, being equidistant (and mostly walking/biking distance) to most important landmarks like Bastille, Louvre, Tuileries , D' Orsay, Champs Elysées /Arc de Triumph , 50 meters away from Hotel de Ville Metro station and bus stops connecting to everywhere (Velo Paris' bike rental station system also) , 5 blocks away from Les Halles shopping/historical district, Pompidou Ctr, dozens of places during daytime and nightlife like boulangeries, restaurants, cafes, bars all concentrated in a 500 meters radius, big time/money saving, a safe area any time of the day, and specially to return at the end of your day.
We were able to get good rest at nights, the place is quiet with comfortable beds, we hang out watching TV (netflix, etc), we cooked, washed out clothes, or just simply chill out, and not a minor thing: it’s got an AMAZINGLY FAST internet connection (300+ MBits!!!)
Owner was great communicating with us before/during our stay, provided tips for grocery stores and places to eat, pharmacies. The place has all appliances you'll need while on vacation.
We could have not made a better decision in choosing this property, I hope we come back soon.
