My mother and I had a wonderful stay in Nathalie’s apartment loft. It’s very spacious and beautifully lit from the skylight windows (the sound of rain falling on the tiled roof was especially nice overnight). The bathroom is large by Parisian standards, with modern furnishings, and the entire unit is immaculately clean.
The unit is however in the former attic, and has sloping walls, which make it an ideal space for shorter people, whereas tall folks may be less comfortable.
As noted in the listing, the apartment is a 5 floor walk-up, and then a further floor on a very tight staircase within the apartment to get to the attic - challenging with a large suitcase. People with mobility issues, or who are particularly tall/large, would find this apartment challenging.
It’s in a fabulous neighbourhood, and I would definitely stay here again!
