I've just had a similar experience in Spain. A guest left six large bags of used nappies in the pantry, and tomato-stained curtains in the kitchen. I left a factual 3* review of her. From her side, a A glowing review, all 5/5 feedback, bland private note, and... a 4* rating. This within 2 weeks of superhost status. I got a warning from Airbnb about falling ratings (another one got quashed). I asked her to up the * rating, she said 'delete your review of me and I'll consider it'. Which is blackmail. I contacted Airbnb support and I pointed out that she gave no negative feedback at all, and the star rating seems to be withheld as a bargaining chip, to force a takedown in case of a negative review. They don't seem to care about this, and say 'it's all just opinions, she's entitled to hers' which is somewhat missing the point because she offers no objective or subjective backup for her * rating. But Airbnb takes it seriously, even if it is inconsistent with every shred of information. So I should just be cynical, take down my review of her, and hope she reciprocates? It all seems a far cry from the warm fuzzy ethos of airbnb, more like racketeering.
