I've been using Airbnb for nearly a decade and am sad to report that this is among the worst experiences I've had.
1. We asked the receptionists about ordering a cab, and asked for a cab that took credit card. We explained that this was a big problem for us the previous day, so to make sure of it because we were going to the airport and didn't have any cash. They called a cab, and the driver and the Airbnb host spoke in Turkish. The host said that the price was 350 TL, including the toll. I specifically asked if that included the toll and asked him to confirm with the driver. He said yes, that was the case. Two things went wrong: (a) the cab driver did not have a machine with cash and we almost missed our flight as a result and (b) the price did not include the toll. We first thought this may have been the driver's fault, but it was pretty clear it wasn't because the driver showed us the meter and said he couldn't ever do credit card. We had actually had the host and the driver talk on the phone during the drive to the airport, since the price wasn't as expected, and the airbnb host did nothing and just said to pay the driver whatever. This was when I told the host that they would be receiving a bad review, and then they said OK they can do something about it, which is pretty bad. We ended just paying more all in cash and nearly missing our flight.
2. The place smelled strongly of sewage - hopefully, this is abnormal but the host showing us the place didn't say anything, and the resulting service around this experience was bad and led to very poor hospitality and accommodation experience overall. We told the receptionists about it. They said they'd fix it for the next night. They didn't and we had to keep the windows open to help a bit, and didn't sleep much both nights we stayed.
I was open to the host that they would be receiving a bad review, so this should not come as a surprise.
