Widespread supposition is that AirBnB does better than hotels lately because: 1) when people do travel, they'd rather be at a single apartment or cabin than a many-person hotel (not saying that's well-founded, just that it's a widespread opinion) 2) some people who are now remote working decided that if they couldn't do anything in this city, they would live elsewhere for a little while.

I have, however, no hard data to back up if these are actually the reasons.
