Great location. Very clean and well maintained. Elevator, laundry, dishwasher, printer, TVs in all rooms, comfortable beds and the ability to control the temperature. QR codes for entry always worked, albeit with occasional repeated attempts (keep the screen bright). The view of the Eiffel tower from the balcony was an incredible perk that made you feel like you were still experiencing the thrill of Paris even when you weren't out seeing the sites. Only had to contact the staff once and they were generous and accommodating.
This "My Maison" company appears to have renovated a number of buildings in Paris and for my taste, it is the ideal hybrid of a good hotel and a good Air Bnb: the maintenance infrastructure of a good hotel combined with the independence and full living space of a good Air Bnb. An excellent and recommended stay!
