Never had problems with guests accepting it. Of course I don't know how many passed me by for it.
Yet if a guest isn't happy with taking on some responsibility for covering damages they may cause, then I'm not happy hosting with that attitude.
Hosts not having a deposit in place are often known to be targeted by bad guests, esp. when renting independent units.
They trash, you pay.
And esp. if you're planning on leaving your listing on the Instant Booking default you'd be leaving yourself wide open for this kind of guest.
