@Russel302 Yes, check the pricing on the guest request both before and after you accept a booking.
I once accepted a request that had the correct pricing, but after the booking was confirmed, I saw my guest had been charged double my nightly rate. I right away called Airbnb, who said it was a glitch on their end, and that lots of guests had been charged double that day.
As soon as I got off the phone with them, I got a panicked message from my guest, saying she wasn't sure if she had misread my ad, but that she couldn't afford the doubled price.
I assured her the original price was correct, that I had already called Airbnb about it, and that she should as well. She did get refunded the difference.
But it could just as easily have been a glitch the other way round, that the guest had been charged half instead of double. So I always remember to check the payment, both when I receive the request or inquiry, and after it's confirmed.
