This is not a residential building, which was explicitly stated in the listing. While there may have been some apartments it was primarily an office building, and so on Sunday (when we arrived) and presumably during the evenings during the week, the building is absolutely desolate, and did not feel at all safe.
It states that there are two bathrooms, which is not accurate (as far as I am concerned). There were two showers but only one WC. While under French law this may be accurate, as a visitor from the U.S. I am unfamiliar with French law. I fully expected there to be two WCs.
Lastly, the listing stated that there is a lift with no qualification of any sort. In fact, there is a lift only to the floor below this apartment and then there is a flight of stairs to get to the apartment. This was supposedly disclosed in a health document, but it was not disclosed in the listing, and in our view, this was very misleading.
If you are traveling as a family there is not nearly enough storage. While there are several closets, most of them are filled either with equipment or cleaning supplies (e.g. vacuum cleaner, mop, and pail). If you are only a couple of people and you travel light you may not have an issue with it.
Lastly, we did not love the area. It was quite desolate on Sunday and we did not feel there was a good choice of restaurants in the area.
In short, this was not a good stay; we left after only one night of our 4-night stay in Paris and checked in elsewhere.
I will say that communication and check-in were good. Even when we were dealing with these issues the hosts were always pleasant and responsive, even if we could not resolve our differences.
