I wonder how hotels could do this effectively and safely.

Include a mini-kitchen with 2 burners and a small counter. Burners are disabled but could be enabled by request, or some keypad on the wall (child proofed). You can pick up a box of kitchen supplies (pots, knives, etc) from the front desk or request room service to cart them up.

Put the supplies back in the box before you leave (box is lined with a rubbermaid dish bin).

This would offset the cost of furnishing each room with supplies, while also killing one of airbnb's value props.
