@Erica1130 While I agree this was a nasty situation and I would have simply apologized and refunded the $, this really leapt out at me in one of your posts- "We had dinner plans at 7pm and had to do “hose showers” outside. It was a nightmare. "
Someone who characterizes having to take a hose shower, because the host couldn't get a plumber there until after you had to go out, as a "nightmare", is someone who, to me, should not be booking an Airbnb, but should have booked a luxury hotel in the first place.
There are plenty of people who would have accepted that plumbers don't just show up the instant they are called and that the host was doing what they could to remedy the situation. They would have been adaptable, grateful that there was at least somewhere to rinse off, and not created a dramatic "nightmare" out of it. And was there really only one bathroom in a house for 7? Could the another bathroom not have been used, even though it was inconvenient?
