They've gotten much much better in the last 5 years. After all the small time would-be "empire builders" who overcharged for shoddy units and abused residential real estate laws got cleaned out of the system, it seems like what's left is a decent middle ground of professional operators running full time rental units, with a few of the original style unique experiences left here and there. The standards have gone way up, and it's generally better than a hotel at the same price point again, which it was absolutely not for most of 2015-2020ish.
Depending on the location you get a bunch of people basically who own a vacation home they get priority to use and rent out the rest of the time. Which is honestly rather nice for both the guests and the hosts.
That was my preferred experience too - well maintained and lived in just enough to make sense. Some places do cheap out on "perks" that seem there only to boost themselves in rankings/filters, but otherwise been a pleasant experience.
We did this in the 80s and 90s so this is not something unique to airbnb, airbnb just did it "on an app". When I say "did this" I mean rented a duplex or house for a couple weeks for a vacation.
VRBO did whole-house vacation rentals in the U.S. well before AirBnB. Still around and works well. I’d say we book about half the time through VRBO and half the time through AirBnB.
AirBnB’s differentiator on launch was “rent just one room” in an owner-occupied dwelling. Remember when it was “the sharing economy”? There are still listings like that, but I think most of the money is in whole-dwelling rentals now.
I genuinely love that 'rent just a room' (or even just a bed!) function of Airbnb, and continue to use it till this day. Have met many interesting people (or as I heard another comment on here say "weird in a non-dangerous way" lol), and it's always felt like a safe and quality experience to me (so long as I always do the due diligence and use common sense to stay with hosts that have tons of positive reviews, etc). IIRC Airbnb had a push a few 'releases' ago to revive this core part of their founding purpose, but now it seems they've moved on to 'services'.
