Pretty much the worst host experience that we have ever had, and we have had dozens of pleasant stays at different Airbnb properties. Both the smoke detector and carbon dioxide detector were completely disconnected and sat unusable on a table next to the TV. Sheets had hairs on them and either had not been changed or were poorly washed. The corporate host was non-responsive through the Airbnb messaging app, so we texted the ‘local host’ as per the house manual who simply replied that we should get a chair & reconnect the detectors (!) and that the sheets had indeed been washed. As we patiently repeated to the ‘local host’, a ladder was required due to the ceiling height. The ‘local host’ claimed to have made many efforts, but the net result was a severe safety issue in this property that was not resolved during our short stay. If not for the last-minute lack of alternatives, we would have left this property immediately. Simply unacceptable.
