I spent 10 days at this lovely apartment on a visit with my mom, and we had a great time! Here are the pros and a few "cons" of the place:
1. Pros: Great, safe neighborhood, near a metro stop, cafes, and shopping but not loud in the evenings. The bed was comfortable, the bathroom/kitchen/living room were well sized, and it was great to have storage in the closets. We also used the washer/dryer a couple times which was great to have done before our flight. And the elevator, which is rare for Paris, was also a godsend for when we brought our luggage up and down!
2. Cons: On hot days the apartment heats easily, but it wasn't a big concern for us as we usually run cold anyway. There were a couple tight squeezes (ex: can't open a drawer without closing a door in the bathoom), and we could have used another towel. But these are all super minor, and all in all we loved our stay.
I would definitely stay here again, though, and appreciated Pierre's communication throughout the trip with whatever little questions I had. We were also just a few minutes away from a pharmacy where we could do our COVID test for returning to the US, and the bakery downstairs is excellent!
