PLEASE READ ENTIRE REVIEW:
The only positive thing I can say about this Airbnb is that it's close to a metro stop.
Before I begin, this apartment is owned by a company that owns about 10 apartments in the same building. If you are expecting the typical warm welcome that you get from Airbnb, forget about it. This is not clear in the posting since you are talking to "Sebastien", but in reality it's an organization.
When you first get into the apartment, you'll notice that there is almost no room for suitcases as much of the living room is taken up by a bed. The beds are actually nice and the apartment is decently quiet for living next to a busy Paris street, but it's definitely a tight fit.
My group of 3 was OK with the size because of location until a series of events put us on the fast track out of that hell hole.
The first event was that the apartment next door to ours was robbed during the day. Again, these apartments are all owned by the same organization, so if one apartment's security wasn't enough, the rest have the same problems. We talked with the people renting the apartment next to us and they let us know that they were planning on leaving because they no longer felt safe there. We were a little shocked by hearing that they were robbed, but it was not the deciding factor on us leaving.
The biggest reason we left was a massive plumbing issue. One of the members of our group decided to take a shower the first night we were there. About 5 minutes in, she stopped the shower and asked us to come take a look at what was happening. When we walked in, there was water filling up the bottom of the shower because THE SHOWER WOULD NOT DRAIN. In fact, there were tiny brown flakes coming out of the drain. We thought nothing of it, she tried to finish her shower and we contacted the organization to try and have them fix it. We were told that, "no one is available now, but we will send someone over tomorrow". Perfect, we thought, and then went to bed. The next morning we woke up and went to look if the water had drained over night. We were met with a horror show. There was feces all over the shower floor. Feces and wet toilet paper. The sewage pipes must have backed up and deposited poop and toilet paper all over the shower floor. I immediately took pictures and contacted the organization. I was told that they were very sorry and would try and get someone over. 6 hours later, we were looking for another Airbnb with no sign of anyone coming to fix the pipes.
Other issues: elevator broken (5 flights of stairs with suitcase), the WiFi is pitiful, the view outside is of the Hilton Hotel (where we wish we were staying instead).
Horrible experience, no customer service at all, they took hours to respond and never followed through on what they said they would do.
I would NOT recommend this "Airbnb" (if you can call it that) to anyone and would highly recommended that "Sebastien" be taken off the site.
0/10 poopy experience.
