Spectacular location! Very easy access to just about everything. Windows overlooking the small pedestrian street below are excellent and if you choose to close them, are effective in making the apartment very quiet. The main room is quite spacious as shown in the photos and the bed is firm and comfortable.
Negatives are limited and associated with being in a historic building a few steps from the Seine: namely, steep, spiral staircase walk up; very small (but effective with good hot and cold water pressure) bathroom and pied-a-terre type kitchen. There is a large dishwasher (can fit all the dishes and pans in the apt), washer but no dryer or drying rack. Cooktop but no oven, but no one is visiting Paris to stay in and cook dinner! There is a preponderance of DIY work in the apt, so if you’re used to the Four Seasons, this might be an aesthetic distraction.
But it’s really all about comfort and utility and especially location, and this apartment excels in that regard. We would absolutely stay here again!
