Want hotel quality and safety with apartment perks? Just go to an apartment hotel! It costs more than a hotel/AirBnB but you're also not at the whims of random hit-or-miss listings and shady shit. And they clean your room if you want them to!
They're not nearly as common as Airbnb apartments in most countries. I also trust Airbnb listings and reviews more than what I find on most booking sites.
Maybe some way to secretly write problems, and get next guests to agree/disagree with each concern?
Repeatable patterns of problems (rather than one-off bad luck) are what I'm most interested in avoiding.
I find booking.com has been more reliable, and less risks of unexpected costs. AirBnB is usually way less professional.
For instance, hypothetically, there might be a listing that mentions plenty of clean towels, a swimming pool, and a walk to a convenience store. I get there and there were two towels, the swimming pool was one of those above-ground models, and the convenience store was a 20 minute walk.
Leaving a negative review on AirBnB might fuck the guy over in search results or certain incentives, so I wouldn't really delve into the definition of "plenty" and how a "swimming pool" should mean "a pool that's large enough to swim in" and not "a big puddle that's perfectly suited for splashing around in, but less so for actual swimming". I might mention them in a private note to the renter or something, but it's not egregious enough to sabotage the otherwise-perfectly-fine service I was provided.
There's no such direct gamification with a third-party review site, so I might bring these things up there.
It's similar to leaving a thumbs up for an Amazon driver who walks on the lawn because he didn't notice the paved walkway. Was it "perfect delivery"? No. But is it something I'd want the guy to have negative employment ramifications over? Also no.
