This is the primary reason I use Airbnb and it's equivalents. My typical traveling party is 4 adults, 3 kids, and 1-2 dogs most of those people have a preference to cook rather than eat out. Accommodating that in a hotel is a disaster unless you get an ultra low price of a double suite or something.
That's really the sweet spot for Airbnb (and Vrbo). Very few conventional hotels accommodate large groups well. If you're just trying to save a few bucks as a couple or solo traveler I'm not sure it usually pencils out given other tradeoffs.
