My wife and I rented this place when we stayed in Paris for a few days. This Airbnb won't have a local vibe but more of a hotel feeling. But the communication is very good from the beginning and the people who are in touch with you will do whatever they can to make your stay better.
Getting into this room was an adventure in itself as you have a gate, front door, another door and then your apartment door to get through with codes and keys. so atleast I can say it's fairly safe feeling. Once in the apartment you have the usual city apartment with one bedroom for 2 people, a living room with pull out couch for another 2 people, a kitchen and bathroom. This apartment is more ideal for couples but 4 people can survive if needed. I have mentioned some cons of this setup below.
The wifi from the beginning was not working for us and I complained about it. The individual helping me told me to restart the router, which I could not find anywhere. I was told the building manager will take a look at it but nothing happened for 2 days. I got soo fed up that I asked for password for another router that was nearby. I don't know why they could have just told me that from the beginning.
The sink in the bathroom was clogged and couldn't handle running water for too long. The individual working with me told me to leave the keys in the lock box outside when we are out so someone can come take a look at it. All though a helpful gesture, I was not comfortable letting someone inside the Airbnb when we are not in there.
Expect the walls to be very thin. You can pretty much hear everything next to you and above you. We were able to sleep at night and no one really bothered us much. But for light sleepers you might want to look elsewhere.
Overall is this place terrible? I don't think it's for everybody. I would not come back here unless this was the only cheap option in town. For extended stays in Paris I would look somewhere else that is more personal.
