If you have another destination, transport from the Schiphol airport by car is much easier. A ride to the city center takes about half an hour, depending on the destination and busy traffic. You can follow the “taxi” signs or floor stickers from the Airport arrivals. These will lead you to the taxi’s that are waiting at the exit of the arrival halls.
Make sure you walk to these taxi’s yourself. There may be people trying to seduce you into a taxi ride at the arrivals hall. Never get into a car of these people, they are bad news. Walk outside, a line of taxis will be waiting there, just choose one if they are available.
A taxi ride to Amsterdam city center costs around 50 euros. The taxis run with a meter, are often good quality cars and they can take you all the way to your final destination. Please watch out for taxi drivers that don’t speak English.
