The apartment was as advertised and in a great location, but we had serious communication problems with the host, whom Airbnb said is named "Marc" but was listed as Pierre De WeHost. I believe we were dealing with an unresponsive management company and not the owner. In any case, there were no responses to our repeated requests for a second set of keys over 6 days. There were two of us, both adults, and we were traveling to different places at the same time. I was working at the Porte de Versaille convention center and my wife was sightseeing. We had to waste time and I had to miss work just so that we could meet somewhere to pass the one key set from one to the other when one of us needed to return to the apartment. When we checked in we were told that they issued two sets of keys only to people staying for more than 10 days, so we knew that a second set was readily available. Our repeated requests were ignored, and AIrbnb support told us that they knew that the host was reading the messages, but they too did not get any responses. The only time we heard from the host was when it was time to check out and he/they/it asked for a good review.
We had stayed in a lovely Barcelona apartment the week before, and the host there provided two sets of keys without us having to ask. The lack of communication in the Paris apartment made us wonder what would happen in the case of a true emergency, or a serious problem such as an overflowing toilet or burst water pipe. We cannot recommend this property for these reasons.
