My experience might’ve been atypical, as other reviews are actually pretty good..
I visited during the wildfire season when air was a documented 290aqi outside while I was on the premise. The window had been left open before I arrived and the it was broken and would not close, leaving a large gap allowing a steady stream of air and wind to bring the smoky air on from outside.
Keith let me know he was sleeping before I had arrived, so I didn’t want to bother him after he had given me a tour of the common area and returned to bed. Thus, I reported the issue first thing in the group chat in the morning and only got denials that the window was broken and/ or that it had been left open before my arrival. Both claims I know for a fact to be false, because Alexis (the other host) let me know that another guest had tampered with the window and so it doesn’t function properly anymore. She just kept telling me to slam the window, which I tried dozens of times and told her it wasn’t working. I even took a video to show her how hard I was slamming it, but I couldn’t send it through Airbnb and she just continued to deny that the window was broken...
After sleeping a full night in the smoky air, which debatably is partially my fault because I should’ve just woken Keith up, and also being told nothing was wrong, I actually also went and got an air purifier to try to clean the air in my room while I was waiting for the situation to resolve. At some point, hours after I told them about the situation, knocking on Keith’s door, and also getting my own purifier, I was worried that I’d have to sleep through the night in the smokey air (still >200aqi) again, so I left. I was also very disappointed that while I had the time to go to target to get an air purifier, Keith couldn’t just come down to address the situation. I’m not sure where Alexis resides, but she was the only person contacting me through the chat that day and was non-reassuring to say the least.
I’ve stayed at Airbnb many times over the years, but I’d have to say this was the most disappointing experience I’ve had. Alexis was condescending and said I just wanted to complain and continually made claims that I knew to be false because I was at the house and she wasn’t...
