All these years of airbnb and vacation rentals being popular and hotels still seem to not try to accommodate these needs

This is my number 1 reason. Eating out is expensive, and it is very hard to do so healthy.

I also don’t feel great after eating out for 3 meals per day. That’s the mean reason we use AirBNB.

Airbnbs with kitchens are especially useful in the US due to the cost of eating out, with tax and tip etc. In other countries I use them more for getting luxury places at a lower cost, such as in parts of Asia, where eating out is much cheaper.

I've rented plenty of rooms with a kitchen, or at least a kitchenette.

Yeah it's pretty good as well, I found it to be more expensive with less selection though.
