We are 67 and 70, fit and active, though as I do all the cleaning and prepping, I am tired and sore, just like you. We get a lot of 1 night stays, and everyone says they should have booked for 2 nights, as this is an architecturally outstanding house in a drop dead scenic place , a destination to rest & rejuvenate. It is not a “stop over late arrival early leaving” type of place, on the way to somewhere else. We do not do instant book, as we are heavily booked enough without and it is important to me to do a search on every guest, communicate with them as well, around their booking. On holidays have a 2 - 3 night minimum, depending on the length of the holiday and when is the weekend. I take rest times where I block the place between guests. At some point I’ll put a 2 night minimum and I will go for quality over quantity. Our guest suite is over 500 sq ft, with a full bath and I tear it down for deep cleaning every change. It takes me 3 full hours to clean and prep, no matter how short or how tidy the guests. Every dish needs to be washed, of course, and every crack and corner cleaned, as our reputation is for spotless cleanliness, so our guests feel that they are not taking a chance on their health.
