@Laura2592 I don't quite understand the concept of having a listing which is fairly remote, yet turning down requests from guests who are looking for exactly that. I understand that it needs to be really clear to guests that there aren't any stores, cafes, restaurants, etc, just around the corner, but for many people that's the attraction of booking a remote listing.
My place is a 20 minute walk into town- I've only ever had 2 guests who had rented car, all the rest walked back and forth daily, or even twice a day. Many of my reviews mention how nice it was to be away from the hustle and bustle.
I do get the concern about being able to get to the place during the winter if there were an emergency, not sure what you could do about that, except make sure they are clear about the fact that they could get snowed in and that if say, the water heater went on the blink, you might not necessarily be able to deal with getting it repaired right away.
