I commiserate with you. We have had only 3 guests so far, and all 3 have had the exact same behavior, despite being at different ages and from different parts of the country. The only thing they have in common is that they're all American and apparently middle-upper class, and I'd hate to think that this is what defines Americans: selfish, disrespectful, noisy, dirty, and above all wasteful of resources.
1.) All the lights and fans are left turned on, even when they're leaving for a day trip.
2.) The doors are not locked, even though they have a key and have been shown how to lock from the inside when leaving, to not have to dig out a key.
3.) Kitchen items are not washed, but just rinsed off, with the water on full blast and splashing all the countertops. The faucet is usually left dripping.
4.) The kitchen is next to our bedroom, and guests come in at midnight or 2am and bang around, leaving all the drawers and cupboards open. They leave their food unwrapped or not sealed, inviting bug problems.
5.) Headphones are not used, and even with our door closed and a white noise machine on I can hear whatever they're watching on a computer/phone (no TV in the home, on purpose).
6.) We have a chair and changing station to take your shoes off at the front door, but guests still come in, two weeks after being here, with their shoes on. Or, they go outside barefoot and come back in with muddy feet.
7.) We invite guests to eat with us at the dining table and explicitly state in house rules to please not eat in the bedroom. They do it anyway and now we have bug problems.
8.) They go through impressive amounts of toilet paper, leave wet towels crumpled in the corner when there's a long towel bar, and one guest dyed her hair and left the place a mess.
9.) We have the trash and recycling bins clearly marked, but they put everything in the trash. Recycling has been around for a long time, so it's incredible that folks still don't know what goes where.
10.) It seems that nobody read the house rules (ex. laundry is not included in the amenities, but they washed their clothes anyway, using our detergent, and letting the dryer run in the wee hours, also next to our bedroom), so I’m not sure what good it will do to make our list of house rules even longer.
I’m tired of cleaning up after adults who act like children, and I’m literally tired because they bang around next to our bedroom very late at night.
We have loved hosting through other platforms (where guests don’t pay—so maybe they feel entitled to trash the place because they paid for it?), but we’re about ready to give up on AirBnB due to this utterly disrespectful behavior by bad house guests.
