I travel a lot (including in SF and NYC) and you're objectively wrong. I prefer hotels to AirBnB, but still almost always go with AirBnB because it's significantly cheaper.
For your suggested dates of Dec 18-20 I found literally dozens of AirBnBs for <$80/night. [0] All I can conclude is that you're straight up lying. It's trivially easier to find AirBnBs which are cheaper than hotels.
Yeah, I have so much incentive to straight up lie. The average for the link you have is $108/night. That's above several hotels in my search. Also, most of these AirBnB listings only allow 1 person. Every hotel room will support 2 people and most will allow 4 (if you can get 2 beds).
Take that for what its worth. If I'm objectively wrong or a liar to you, cool.
