Whenever it's possible, I use something else, like HostelWorld. Their interface is clean, to the point, and the reviews and ratings can actually be trusted.
I'm happy someone did this website. I just came back from a long trip and every time somebody asked me why I hate Booking.com, I pointed exactly to some of the points that were made there. The fake sense of urgency, the cluttered UI. And the cherry on top: The fact they display the "total cost of all nights" in the results, instead of the per-night cost. That's not a misleading UX, it's just a bad UX decision.
But because of it's popularity amongst accommodation owners and travelers, its fall is unlikely.
