@Verna48 It depends on what the agreement is, but I think it makes sense that if it is a whole-house rental, and it is the same price for 1 as it is for 6, then all the bedrooms should prepared and made available to the guest equally. The guest might want to try them all out to see which one they like best, a la Goldilocks. Or they might want to sleep in a different bed every night. If the guest has paid for the whole house, then all of the bedrooms should be part of the package.
I think this is what most guests would expect, but of course as the host, you can tailor your offerings however you like. If you’re offering less than the whole house, though, or it’s varies depending on the number of guests, make sure you make that very clear in your listing.
