The hotels have been downgrading the quality around their brand names for years now, cramming people into tinier and more cookie-cutter spaces. Plus the average Airbnb has always had more livable space (not to mention a kitchen!) than a hotel. For 190 a night, you're probably getting the whole Airbnb unit to yourself.

Take that, and SF's 14% hotel tax, and I think they're reaping what they've sowed.

It's not unusual for airbnb to be more expensive than hotel.

When I was in vietnam, all I had to do was go around to a couple of hotels and ask for the price in person.

Many hotels are not advertised online. And even though the space is smaller, I prefer it over airbnb. More anonymity and room service.
