It gets the job done. But maybe that's not the UX itself but Booking.com's usual "no payment, free cancellation" deals. I often just find a hotel that looks okay and book it straight away. I check out the reviews later and cancel if something doesn't look right.

I believe their point was that the "UX is good (conditions applied").

Also, If you have not tried, I'd recommend giving the (android) app a go, bias aside, its one of the smoothest look-to-book experience I've had.
