My second worst AirBNB experience and I've only had two bad experiences in over 8 years.
The host was very uncommunicative to the point I need to remind them to send instructions for check in, the host did not reach out to inform there was no heat in the unit unless I paid upfront for it (house rule was cryptic about this), I'd often need to wait hours for a response and in one case I needed to involve AirBNB who agreed the host was unresponsive.
The kicker is that in addition to not being communicative, the host allowed others to enter while I was out to install an AC/Heater unit that, overnight... started to detach from the wall. I messaged the host in the morning with photos of the unit. After an hour and with concern for their property, I involved AirBNB. A full SEVEN hours later, the host finally responded very angrily at me for involving AirBNB. Then the host proceeded to harass me with repeated private messages despite being asked to cease.
Location is also unpleasant.
