Agreed, the main app prioritises showing you gimmicky tree houses over places which are much more interesting (perhaps with a more convenient location, or remote work friendly for 2 people).
They are probably trying to push back against the commodisation of AirBnB stays. In the last few years they seem to have become extremely standardised, within a certain price range and star rating you know almost exactly what you'll be getting in terms of service, cleanliness and outfitting of the apartment. I like it a lot as a cheaper alternative to hotels for longer stays! But perhaps lower margin than littering the countryside with wacky constructions.
