@Ale19826 The individual category ratings don’t affect your overall rating. Try to learn to let it go when this happens, as it will happen again, and in other categories. Focus on what you can control, which is being accurate in your listing details, and providing the best guest experience you can, and you’ll do fine.
Even if you explicitly describe the steep and curvy roads to your listing, you are guaranteed to get another guest who will do the same thing. You can’t control that, just as you can’t change the hills and roads.
