I have read that AirBnB gets into a lot of issues with travelers in regards to many things, refunds being a good percentage of them. Was that your whole stay or "just" a deposit?
I know they're trying to look out for the owners of the property (supposedly) and their cut in it, too.
A cousin of mine was stuck in Europe, trying to fly home, during that computer outage. She said it was a great thing that they had purchased trip insurance! They could get things that the average person couldn't get, because the airlines would take them home as soon as they could, but was not being cooperative with overnights and meals.
