I am writing this with the hopes that AirBnB will post the entirety of this message for the safety and wellbeing of the wider AirBnB community. To sum it up, Mac's apartment is not rent-able. The furniture is old, worn, stained, and unusable. The carpets are warn ragged. There were stains in the toilet (see below for a fuller description). There was even trash left in the corners behind the furniture that Mac had missed. Finally, there were bugs in the carpeting and bedding that bit us.
The filthiness could have been survivable--just one bad, horrible luck of draw of the AirBnB deck of options. Unfortunately, though, Mac took a horrible trip and turned it unsafe. Without any warning or advance notice, Mac showed up at our rental door to tell us that we were "wrong" about the unit being dirty. We had sent him a message upon arrival to let him know there was some trash on the ground and the toilet was dirty. He raised his voice and barged into the unit without any permission and without a proper facial mask. He walked directly to the bathroom, looked at the dirty toilet, and told me a plumber had left a mark in the toilet bowl. He grabbed a toilet brush and, in less than a couple strokes, cleaned the mark off entirely from the toilet. He then repeatedly, and angrily, asserted the apartment was clean and that my wife and I were simply wrong about the dirt we saw. Quite an oddity, then, that he just confronted the exact dirt of which we had complained. He rattled off--refusing to be interrupted--stats about how little he makes off each rental ($65) and that he takes pride in his cleaning abilities.
We asked him to leave three times and he just kept berating us about how he is a great host and the apartment is clean. I finally told him we needed to leave the apartment because I could tell my partner was worried about her safety. We received a cancelation alert from Mac about an hour later. No explanation. Nothing. We wound up having to book a last-minute hotel that was out of our budget and buy meals in restaurants because we didn't have a kitchen.
AirBnB is working to make this right and I hope they're able to do so. Based on the other comments, though, it looks like the answer is simple: Mac is not a safe member of the AirBnB community and AirBnB has a duty to prevent him from endangering another guest. I recommend that you do not rent this place.
