This was my first bad experience with AirBnB.
Less than 24 hours before I left, Duane claimed additional fees for a failed self-checkin (due to a technical issue on my end) and for early checkout. I asked her to claim these fees via the AirBnB system. She demanded either immediate payment (against the provisions of the Resolution Center) or to check out after 10 (not possible for me) or to leave the place before the end of the stay. AirBnB should not tolerate this kind of practices.
Duane's way of communicating was inappropriate. She clearly had difficulties remaining factual and polite throughout the dispute.
The AirBnB support was on and off and gave me contradictory instructions, which did not help in this hectic situation.
On a more positive note, the flat is a Parisian masterstroke in making the most out of small spaces, tastefully decorated and very clean. Not made to hang out, though, as there is no comfortable seat. Better for travelers who are out all day.
