Yeah, I'm fairly sure this building was paying for good reviews and paying tenants to take down bad reviews. In fact they did waive a hefty fee in exchange for me removing mine. I wish I had enough money to tell them to fuck themselves on that one, but I don't.
Most of the reviews at this place were either glowingly positive or very negative, citing the same kinds of severe maintenance issues that we'd had there. But the catch was that you'd almost never see the negative reviews unless you sorted by most recent. A fact I learned after it was too late and we were already moved in and having terrible experiences there. Basically Google was helping them bury the reviews that made them look bad.
Also originally Google had silently hidden my very negative review. I tried removing a phrase about how I was sure the apartment complex was breaking the law and it magically showed back up... The whole damn thing is suspect. I no longer put any stock in reviews.
Edit: I just went looking back at the reviews for this building and I found out that Google removed the only small power the public has against fake reviews. The "not helpful" button was replaced with reaction emojis, all of which convey positive emotions. Fuck Google. They know they are helping shield bad businesses, they just want to keep clicks (ad dollars) flowing.
