I don't even think we need a location accuracy rating. We already have an accuracy rating and that should cover any aspects of the listing, including location. In my opinion, Airbnb should just get rid of the location rating altogether, because there is nothing a host can do about it other than provide an honest description (which would be covered under accuracy anyway). But, this has been said on these forums over and over again. I would be very surprised if it hasn't been brought up repeatedly in the Host Voice forum, so I don't know why Airbnb doesn't address this.
My lowest ratings are also on location. It's the only category where I've received three stars (interestingly, also most often from Americans, but from other nationalities as well). Most of my guests love the location because it is so convenient, not just in terms of transport and getting easily and quickly to all the tourist attractions, but also for all the supermarkets and cafes within a stone's throw.
However, I do think others come with a preconceived notion of what London looks like. They expect something from Downton Abbey, where everything is oldy worldy and everyone is white, as if two World Wars, the Blitz and decades of immigration had never happened! Unfortunately, many people are totally unaware that London is one of the most culturally diverse places in the world. I have travelled to many countries and sadly the most common reaction when I tell people I'm from London is, "No, you're not. Where are you REALLY from?"
@Tamara2 I agree that mentioning your listing is close to Notting Hill is a mistake. That may be totally accurate and a host should be able to mention this as a selling point, but people don't read properly and so they expect Notting Hill, but end up in Shepherd's Bush and disappointed.
By the way, Notting Hill is a very ethnically diverse neighbourhood, not spotlessly clean and you are as likely to get mugged or molested there as anywhere else, but newbies to London will expect Hugh Grant and quaint bookshops!
Ok, rant over!
