Same, I've only ever had positive experiences with places I've stayed, except I'm in the US. I don't know where everyone is going here that they're having such awful stays. Then again, I've only ever stayed in places that aren't company owned. I do several months of research before picking a place. I check reviews, fees, etc, and avoid corporate owned properties like the plague. There are no surprises with if you just take the time to look.

After my stay, I take the time to write an honest review of the property. Things that were good and bad. Not just some shitty single line "We had a great time! ⭐⭐⭐⭐⭐"

If you find problems, report them to the owner, include them in your review, report bad actors to the site or if need be, the authorities. It's your responsibility as a user of the platform. If you don't, you're part of the problem that's dragging the platform down.
