The thing is, @Inna22 can't prevent a light bulb from burning out during this stay unless she goes in and changes every single bulb, which would be silly. Or, god forbid, what if something breaks? Plus, who is to say, maybe this guest is one of these nightmare people who break everything, perhaps she broke the stove and clogged the toilets at her last rental.
I would say something like 'Sorry to hear of your previous bad experience with an Airbnb. Please be assured that the house/apt is professionally cleaned before each guest and appliances are in working order. Should any problems arise during your stay, or if you have questions on how any appliance/feature works, don't hesitate to reach out.
