@Dean686 I don't believe there is an Airbnb policy on this. Even if it's disclosed in the house rules, house manual or listing description that the host will need to be accessing the space during a stay for whatever reason, it's good etiquette to contact the guest and arrange a visit that is mutually acceptable. You can speak to the host and let them know this made you uncomfortable, and either come to some understanding, or let them know you'll be checking out early because of it, and would appreciate a refund for unspent nights.
