Have to agree. Die hard Airbnb user for years, then recently using booking.com more and more as it's clear and obvious what you are paying for (in most instances), and no insane "we're not a hotel, so change the sheets, wash them and put the rubbish out in these specific bins" list of exit rules.
Accidental discovery, but have to say they've helped far more than hindered (especially with last minute bookings in distant lands).
