That's probably true. Your chain midrange business hotel probably has some rooms that aren't in a great location and maybe it's a bit overdue for a refresh. But I can't remember the last time I had a genuine problem with a hotel whether room availability or billing.

I have used Airbnb once. And it was quite pleasant. In a tourist area where the hotels were really pricey and this was somewhat cheaper (though not cheap)/likely better. So it worked out. But I'm aware it's probably a bit of a crapshoot.
