This was our first Airbnb experience and Ariane made it a positive one for us.
She was there waiting for us to let us in and gave us a briefing about the apartment, local shops and Paris in general. She even welcomed us with a vegan chocolate bar since she knew my wife was allergic to milk. She very quickly answered to any questions we had during our stay.
The place is not luxurious buy has all the basic ameneties one might need. The apartment as mentioned by others is very close to the metro and shops.
One small problem we experienced was the noise early in the mornings (between 6-7 am) coming from the main enterance creaky door (which was just on the other side of wall where the bed was) and people going out of the building. I personally woke every day because of this noise which for me wasn't really that bad since it gave us more hours to explore Paris. But if you are a light sleeper and like to stay in bed till later then this might be a problem. The flat is literally next to a clinic/hospital.
We were very happy with the place and would probably book the same place for our next visit.
