@Timothy319 You should be aware that some guests will book a place for a week to take advantage of a weekly discount, but then come up with an excuse why they need to leave earlier, when that was their plan all along. So if a guest demands a refund for unstayed days in that case, they could just be scamming. If they don't mention a refund, then of course they would be telling the truth and if a host feels a refund is something they want to offer, that's a nice gesture.
And if you haven't gotten paid out from Airbnb for the booking, don't issue any refunds until you receive the $, as a guest could ask Airbnb for a refund, receive it, and the host is out that money twice.
