The location of the apartment was as advertised; the neighborhood was fine, there was easy access to Metro, grocery stores, and restaurants nearby, as well as a laundromat.
The apartment is typical size for a place to stay in Paris, as long as you know to expect tighter quarters. We did not have any particular issues with this, but anyone wanting space to spread out may have a hard time.
It is also a ground floor apartment, which is nice for those who have trouble with stairs or plan on hauling more luggage. It is right by the front door of the building, though, so you do hear every time anyone in the building goes in or out at all hours. If you are light sleeper, you may want to bring earplugs.
Everything was clean when we arrived.
The issues we did have mostly stemmed from communication: our host set a time to meet at the apartment, but we stood outside for about 15 minutes before someone else showed up as a representative. He was very friendly, but we did struggle with our very limited French and his lack of English to communicate, as no written instructions or information was provided. Obviously, being in Paris, it is not a default expectation that English has to be accomodated by any means, but be aware that if you have no French ability, you may have some difficulty.
When we tried the wifi, it said the password was incorrect, and he indicated he would have the host contact us within a few minutes. We waited for a while (during which time he returned with another man to work on replacing lightbulbs) and did not hear from the host. Upon reaching out, we were sent the same information over again, and when we responded that we had already tried this, we received no further reply.
As a heads up, there was one outlet that would trip the circuit if anything tried yo draw power (including the lamp that was plugged in upon arrival), and the door to the living room can get stuck, trapping someone inside. The latch can catch in the doorframe, but there is no handle on either side to turn.
On our last night, we were messaged at a quarter after midnight asking what time we planned on checking out. Check out itself was simply leaving the keys in a designated spot, so that was easy.
