Catherine was a wonderful host, and the apartment is charming, functional, efficient, and conveniently located. If only the apartment itself and the attributes of its host were to be reviewed, this would be a straightforward and completely positive review. However, the apartment building was a factor, and not a positive one. There were wires hanging down in our hallway. The floors were in poor repair, and although they were said to be in the process of updating, that was a slow and unpredictable process. (We were trapped in the apartment by wet concrete for a time, and never really knew when our return access through the ground floor would be impeded by new concrete there, too.) Until our last day (out of nearly a week), the elevator call button on the ground floor was nonfunctional, requiring us to use the stairway to climb three flights during the hottest Paris week in recent memory. And the first floor and stairwell had a bad odor. We recognize that this was not within Catherine’s control. Throughout all of our challenges, Catherine was very responsive and apologetic. Nevertheless, the building issues had an effect on our visit. If the building would be more functional and not have such an odor, we would offer an unqualified endorsement of this AirBnB offering.
