Do you have any specific one in mind? Because while it's nice to blame Google, my experience has been quite different.

I just tried the last two boutique hotels I stayed at. For one in Tel Aviv the Google and Brave results were exactly the same. First was the hotels' own website, second was tripadvisor, third was booking.com.

The other in Buenos Aires, Google had the same order (hotel, then trip, then booking), Brave did not. Brave showed booking.com, then hotel website, then tripadvisor.
