Hi @Martin6
Thats one of many platform areas that I’d appreciate updated as well.
I know of no way to accomplish thus except by stating it in the narrative of the “host contact” and general property descriptions.
I always send a welcome message a couple of days before arrival to answer any last minute questions, discern an eta, and offer directions. In that message I let them know that after a certain hour, they can self check in, i’m available via messaging, and I’ll catch up with them in the morning.
So far, the message endeavor has been successful over putting it in the listing, and it’s much more personal.
