We had to change our Listings. While we've had guests with children who were very responsible AND who were very good about ACTUALLY READING OUR LISTING (what is it with guests not reading???) such that they were well informed that we have stairs but no child safety gates, that children must not be left on their own in the gym area with the exercise equipment, etc., we did nonetheless end up with a couple of bookings with families who hadn't read the Listing, or hadn't considered what they'd read, which led to BIG issues.
Now in our rules we're requesting that all children's ages be listed in the initial contact (why do so few guests actually follow that 1st & very simple rule of airbnb's, about telling us Hosts about themselves/their group & about why they're needing accommodations?), & reserve the right to cancel if they do not supply us the basic info, as they're obligated to do, straight away. We all have that right now, with the new proviso in Instant Booking, but to have it in our House Rules, we've noticed our guests are now always remembering to give the basic info when booking... (We don't like to have so many House Rules! & we wonder if it is off-putting to other guests, having to state these things explicitly in our Rules?)
It sounds so harsh... we're parents, too - so we know that parents, especially of young children, need & deserve society's/our community's support. (And, to read our reviews, one can see that we're big ol' softies - my wife's cultural background/beliefs about the obligations of Host & Guest go way back. Also, our set-up, our airbnb space, makes this possible - some places/spaces/guests just don't need that much attention, but our place works well for this level of, as our guests have said, "spoiling" of them.)
HOWEVER, not all travelers (in general) seem to have the same understanding about what it means when they sign on to airbnb & sign-off on having read the rules, about expectations in communication, and etc., etc., etc.... Over-tired & over-busy traveling parents with young children - our experiences have led us to think they have an even harder time having the same understandings of their obligations as guests & members of the airbnb community.
So, we've had to change. Hopefully, in future, there'll be a way to make further changes, such that those parents of wee ones who are responsible can book with us again. If we stopped using Instant Booking, we could more carefully vet for situations like this... but guests LOVE Instant Book (we do, too - when we're the guests)...
