I found out that the host had double-booked this apartment (with another service I'm assuming) when I landed at the airport in Paris—and I only found out when I messaged them to confirm check-in details. They were kind enough to offer me a place to go while I found a new booking, but it wasn't especially helpful as I needed to be on the phone and on a computer with Airbnb immediately to find replacement lodging, which I couldn't do while in transit from the airport. This may be a lovely place to stay, but I was never able to stay there.
