Hi there, I read your request for assistance In the area of your struggle, I agree with all the posts and would like to add, I have placed a laminated one page of house rules, which includes no eating in the bedrooms, no smoking in the house and or building, also on my list I ask guests not to sit in beds with soiled and or wet swim suits, this helps tremendously. I do ensure packed away clean linens for those back to back bookings and since its self catering, guests with a nudge do clean up after themselves. So just the changing of linens and cleaning floors, furniture needs doing, yes, time is still the essence, but do add to your list of house rules to leave the home as found. This one sentence has helped me tremendously.
