Amsterdam is the hoofdstad (capital city), where according to the constitution, the sovereign must be sworn in. The Hague (Dutch: Den Haag or 's-Gravenhage) is the Netherlands' regeringszetel or residentie (seat of government, residence of the monarch). It is the seat of government, the home of the monarch, and the location of most foreign embassies.
Amsterdam is a city of tolerance and diversity. It has all the advantages of a big city: culture, entertaiment, international restaurants, good transport - but is relatively small, quiet, and largely thanks to its canals, has a little road traffic. In Amsterdam your destination is never far away.
