I just want to share what happens to me just a few days ago. Maybe it can help other hosts.
A guest booked for four night maybe 3 months in advance.
They checked in around 6 pm, but just few minutes after there was power outage.
The power outage was due to a car accident and 3 electric poles fell down.
The whole city was total black out (even our house located 1 hour away, and our other listing at the other side of the city were affected).
The guest called me, just few minutes after check in, and we explained the situation, assuring them that usually it will not take too long.
We called the electric company and they said that they are on going to fix it.
So we informed the guest about it.
About 15 minutes later the guest message me saying that they want to cancel their reservation and get a full refund, as they cant stay without electricity for 4 days!
We refuse, and explain them that the problem is temporary, and that there is no place to stay currently because the whole city is affected (unless a hotel with generator).
Then 2 hours later they message me saying that they found a place (at the other side of the city) with electricity.
We told them that if they have electricity its surely because they have generator.
The electricity finally came back around 10 pm, then I message them to inform them and to apologies for the problem, and that I hope they will have a great stay even though I understand that having no electricity was really an inconvenient.
Since then, no reply, so I thought everything was fine...
3 days later, I received a message from a case manager, saying that the guest might have full refund because our place doesn't have electricity.!
We submit all the documents we had in our hand, like the screenshot of our conversation by sms, and also the proof that there was emergency light in the house. But the case manager was a bit rude, and the next day without even informing us, deducted the full amount to our payout, and refunded the guest!
The case manager, was close minded, and close our case very quickly.
We were hopeless,
We finally called airbnb, let a message to them in the app, in messenger, and in twitter.
We explain them that the guest never let us know clearly that they checked out that day. Saying that they found a place with electricity, doesn't mean that they check out, it might also mean "You are a liar, the whole city is not affected", or eventually even they left that night, they might come back for the rest of their stay.
The booking was cancel only 4 days after, the day of their check out.
Airbnb finally reopened the case! They understand our side, and adjusted our payout, we received 3 nights payout instead of 4 nights.
The guest was still refunded 100%, and left a review (highly negative) but at least we have our payout!
