@Alex6406 There is absolutely no way you should expect or trust your guests to clean the place to a standard that would be acceptable to the next guest coming to stay. That would just be inviting low cleanliness ratings and bad reviews. And not charging a cleaning fee won't solve that.
I'm assuming you live far from the listing, so can't do the cleaning yourselves. When you say it's very remote, that means there are no other full-time residents in the area? If there are, you might look for someone who would like the job who lives nearby, rather than a professional cleaning service. Perhaps an active, retired senior, or a responsible high school student trying to finance their college tuition, or a stay-at-home mom.
