The collection is fantastic, top-tier in Europe. There are a particularly large number of Bruegel's works, along with three Caravaggio paintings, one Vermeer painting, and numerous works by Titian, Rembrandt, and Rubens, all of very high quality. The building itself is also very beautiful, with a stunning cafe. A special commendation goes to the many comfortable sofas inside; you can rest when you're tired and continue exploring to your fullest.
