@Kamah0 That doesn't sound like a very well-thought out plan. The square footage of a home, when it comes to cleaning, isn't all that relevant. Bathrooms require in depth cleaning and sanitizing, so a place with 1 bathroom is going to require less cleaning time than a place with 3 bathrooms, regardless of the home's sq. footage. A place that sleeps 8 people is going to require more cleaning than a place that sleeps 4, regardless of the size of the house. Some listings may only have a changeover of guests 4 times a month, some may get mostly 1 or 2 night bookings, necessitating 15 or 30 cleanings a month.
Some places accept pets and may require extensive and intensive cleaning to get rid of pet hair. Some places are easier to clean than others, with all hardwood and tile floors as opposed to carpeting. Minimalist decor is easier to clean than homes which are crammed full of stuff.
With your pricing model, I would not be confident that corners wouldn't be cut and inadequate cleaning done when you find out that you are being required to do far more work than you bargained on.
And how would it be equitable for hosts who only need 4 or 5 cleanings per month to pay the same as hosts who require 15 cleanings?
