Another not quite chronological thing Airbnb does to the reviews is relegate even the newest reviews according to language.
Meaning that if you're on the English language version ( .com) you'll first see all those in English. Any review in another language is thus buried somewhere behind the English ones but is first on the French (.fr) site.
Even if it's the latest review as in the case of my last guest.
So that last super fantastic review - if it's written in any other language than English, even if you proudly added the translation in English - will not be visible, except for those countrymen or women looking at their language version.
In a slower booking period that'll also make it look as if you haven't had a new guest for a while, thus also giving a crooked impression.
However, this isn't always a bad thing, as in my case of a bit of a nit-picky guest witha foot injury (despite my clear description and pics of stairs, duhh), her review was happily in Portugese, so that one dodged me.
With most guests coming from other countries whose language isn't English anyway you could use that to your advantage with those of whom you assume might leave you a less than glowing review. Just suggest they are welcome to leave it in their native language ;D
