@Liv I do not offer any special amenities for children of any age, and I don't do anything differently for any guest that stays with me. All guests are treated to the same experience.
My space is best suited for folks who are in town with a purpose - visiting family or friends, or attending events such as concerts, sporting events, weddings, graduations etc etc. They are out most of the time. It's not comparable to a holiday home, for example, where folks spend a lot of time in the space.
Also, since I do not have a storage room filled with items from my own kids, since I don't have any, there are no books, toys or games suitable for children. The last guest who asked if I would accept his 9-year-old mentioned that the child was quiet and respectful, and spent most of his time playing Minecraft. I was fine with that, since he had prior good reviews.
Honestly, it's really a bit annoying to be continually pushed to accommodate guests that one's space is not designed to accommodate.
