It was by far the worst experience I've ever had on Airbnb.
The check-in instruction was misleading and it took me some time to understand what to do. I sent a text and called the number but nobody answered. I had to wait for 30 minutes or so to get a response.
Even after I figured out how to pick up the key, I had to wait several minutes in front of the building I received an access code.
When I managed to enter the apartment, I found the room uncleaned after the last guest left. The cleaning team had arrived shortly after I informed the host of the situation. However, I had to wait until the cleaning was complete.
I had to change my evening plan because of that.
The room was okay.
A guest would have to pick up the key from a different place. I would not recommend this place if you arrive with a big suitcase or do not know well about Paris.
