Stedelijk Museum, Amsterdam
About museums in Amsterdam, of course you have the world famous Van Gogh museum and the Rijksmuseum. In this last museum you can find the Nightwatch of Rembrandt. (Both near the Museumsquare). Then you have the Stedelijk museum (also in that neighbourhood). These three museums certainly are worth a visit, I think.
Another famous place in Amsterdam is the Anne Frank house. You can find that at the Prinsengracht (in the center of the city).
In the south, near the Vondelpark is the museums plant with of Stedelijk museum of modern art, van Gogh and Rembrand's museum. I liked Stedelijkt museum most, having paintings of Dali, Miró, Ernst, Kadinsky, Picasso, Mondrian and many more.
