What has happened to Airbnb? Why are guests so bad?

I’ve been hosting for three years. The last guest turned up at my house drunk, took his shoes off to release a cheesy foot odor that I could taste but still declined a shower and drank another bottle of wine while I sat with him. Then within one hour after I went out, he broke my ceramic toilet lid, left his light on, went out, and wouldn’t respond to calls. Unfortunately, I have to say, though this person was a little extreme, most guests lately are just rude and horrible. Is it because Airbnb encourages through their advertising that people ‘make themselves at home’ at another person’s house (read, hog the bathroom and splash water everywhere, sit around in the open-plan kitchen all day, help themselves to condiments from the cupboard, get packages delivered that hosts have to pick up because it’s their address, get drunk in their room, slam doors while people are sleeping, etc)? What is the solution? My house rules are comprehensive. Should Airbnb politely ask guests to mind their manners while they are in another person’s home?

Distributor Kept us Awake in this Loud NYC Airbnb

This was my first experience with Airbnb, traveling with my sisters and daughter to New York City. We thought renting an Airbnb so everyone could have their own rooms would be a great idea. The host would not give us the exact address until three days prior to our stay, yet her refund policy was strict: no refund for a cancellation within seven days of a stay. The reviews on this Airbnb were all positive and there was no mention of noise from a water bottle distributor under the apartment windows… until two months prior to my stay. I have stayed in many cities (none using Airbnb) and know that they can be noisy, but all four of us felt like we were sleeping on the streets that night. To top it off, the water bottle distributor began operations at 4:00 AM, with fork lifts going forward and backwards (including beeping) from then throughout the morning. No one in my party received more than a few hours of sleep that night. So as not to ruin our entire vacation we contacted the host and said we could not stay because of the noise, which was not mentioned anywhere in her post. The host would not negotiate any refund whatsoever. In order to save our vacation and get some sleep we were forced to vacate and move to a hotel for the remaining three nights of our New York trip. My next step was to contact Airbnb. They took my comments and I sent some photos of the window air conditioner that had openings to the outdoors and the street view of the water bottling company next door. After a brief review of the situation, Airbnb denied my request for three nights’ reimbursement. In a hotel one has the ability to change rooms if one isn’t satisfactory. There is no such option with an Airbnb. I will never use Airbnb again.
