This is a great find. The location is fantastic for the incredible food scene in the 11eme arrondissement. You are a literal two minutes from Septime. The metro is 30 seconds away at the corner, so you can easily get anywhere in Paris.
The apartment is otherwise well appointed with anything you could need. Very clean. Stylish design.
Pierre made the check in and out very easy. Our arrival was unexpectedly moved up by about 8 hours, and he helped ensure we could check in our I thought problem. Very responsive and helpful!
Only note, as others have said, would be that anyone with difficulty climbing stairs best avoid this spot. We found the very narrow and steep stairs quirky and fun for a short stay, but anyone with mobility difficulties would have a tremendously difficult time navigating this spot.
Overall, would absolutely come back here. Great host and apartment
