I never met Sophie and I never talked to her. I strongly believe that Sophie does not exist and is just an avatar for a real estate company, the kind the City of Paris is trying to eliminate from the Airbnb business.
That said the apartment is located in the district of Ternes, a very pleasant part of Paris. However, it is located at a 15 minutes walk from Etoile, the most convenient metro station. The apartment is small but very well furnished and decorated with taste. It is located in a recent building of good standing.
Unfortunately, we experienced a few of the weaknesses. First, to get the key for check-in, you must go to a restaurant located at 15 minutes walk from the apartment, which is not fun with heavy suitcases, it is even unacceptable.
The bed is narrow, very uncomfortable and difficult to access. Then the supplies are unsatisfactory: 1/2 roll of toilet paper, no garbage bag and of course no shampoo.
The tone of the communications from the owner can be threatening, for instance, the threat of financial penalty if the apartment is not vacated by 10 am. Regarding check-in, I only obtained the desired time by threatening to cancel the reservation.
In summary, the relationship with the owner was inexistent or negative, not at all the Airbnb spirit.
