It depends on the guest. Some actually read the description of the property, others don't, and book it on the basis of the photos alone.
There's so many issues with the Airbnb ratings system, that it's not worth worrying about.
But it's always important to try to make it clear exactly what you're offering, and deliver the best accommodation you can, so that the guests you get are the type that are looking for what you're offering. If they miss some important aspect, they may be unhappy and give you a bad review, even though it's their own fault for not reading the description.
We're in the countryside, and we go to great lengths to make that clear. Dont book it without a car. Yet, we still occasionally get people who show up in a taxi, with no intention of hiring a car. And we'll always get a lower rating for location because of it.
Nowadays, if I sense from the guest inquiry that that haven't read the description, I always point out that we're not in the middle of town or resort area or next to any major attractions... and they need a car... before they book.
