Do not book this appartment! Never!
I have been using Airbnb for years as a guest and was always to happy with my host. This was the first time I had a severe problem and needed to leave the appartment and cancel it because I was not feeling safe anymore. The negative points:
1. The flat was quite dirty (especially the bathroom) and has a nasty smell. The bed was not made (which I have never experienced before).
2. I booked for 2 persons, but there were only sheets for one person. When I asked the lady kindly for sheets for the second guest, she was getting so angry and accusing me on the phone.
3. The available bed sheet fabric was torn on one side, which made a bad impression. Also, there was a big disgusting spot on the duvet, which I fotographed and complained about at Airbnb, because the lady was not willing to talk to me in a friendly and sensible way.
4. The official check-in time I booked was 15:00 in the afternoon. According to the Airbnb customer service, the host has to stick to that. But the lady was kind of forcing me with many stressful messages before my visit to come earlier. I kindly agreed to come between 8.30 and 9.00, although it was really not fitting in my schedule. When then there was a delay in the metro, and I came at 9.10, she was so much complaining about my delay of 10 minutes - although it was a nice gesture of me to fit to her schedule!
5. Overall, I tried to be really friendly to the lady and only asked her about second sheets for the second guest, but she was getting so offensive that I felt so unsafe and immediately wanted to leave the flat, to which the Airbnb customer service kindly agreed. At the end this costed me a lot of time and nerves, so if you just want to spend a nice time in Paris, do not book this appartment.
