@Niamh54 I wouldn't consider the home to be pet-friendly if I were required to leave my dog alone in a crate all night, where she would feel like she was being punished. It would cancel out the benefits of traveling with a canine companion instead of putting them in a kennel.
No doubt there are some pet owners who would be fine with this arrangement, but given your preferences, it doesn't sound like guests with pets are a good market for you to target. Your reviews are fantastic, largely because you've provided the optimal version of everything you offer. Why put something on the menu, if you can only deliver a suboptimal version of it?
