@Calvin173 Cleaning is everything. Guests expect things to be absolutely pristine and sanitary and will let you or AirBnB CS know if they find an errant hair, a dust bunny, an enthusiastic spider, an escaped toast crumb, etc.
You may think that I am joking, but having a really clean property is key to a satisfied guest and a great review.
I have a housekeeper who does the cleaning, but I also clean the property myself. This ensures that I stay aware of the time necessary to clean and that we can trade off as needed for our own vacations or jobs. I purchase all of the cleaning products to be used, and my housekeeper advises me when to replace things like towels, sheets and kitchen/dining items.
