I don't get the location rating. We generally get high ratings for location but have had locations as low as a 2 and a 3, but only when the person booked without either asking or checking out for themselves the proximity of where we are with the place where they wanted to be. It really isn't the hosts fault if the guest can't read a map or doesn't have the gumption to ask the question.
I certainly don't get the point of ratings for "location" and "accuracy". Listings include a pin point on a map, saying where a place is, surely a host should check this for accuracy and be able to raise any problem with airbnb. The issue of location is (or should) surely be dealt with as a question of accuracy.
