Frequent direct air service is available to major U.S. cities from Madrid and Barcelona. Both Madrid and Barcelona have good bus service between the airport and downtown. Taxis are easily available at major cities all over Spain.
There is a good highway network linking major cities in Spain. Secondary roads are poor in Galicia and Asturias (in the Northwest). The Spanish railway system is extensive. There are high-speed trains from Madrid to other major cities (Valencia, Barcelona, Seville, Malaga, etc.). Madrid and Barcelona enjoy excellent railway systems in their metropolitan areas. Buses and the Metro (subway) in Madrid and Barcelona may be crowded during rush hours but provide fast and efficient service.
Telecommunications to and from Madrid compare favorably with those in any large U.S. city. A direct-dial telephone system links Spain to the U.S. and most of the world. Calls to the United States may be charged to international telephone cards such as ATT (900-99-00-11), MCI (800-099-357) and Sprint (900-99-00-13). You can also use these numbers to place collect calls to the U.S. or for international directory inquiries if you own any of the three calling cards. If you do not carry an international telephone card, you may also reach the local international directory by dialing 025. Due to recent changes in the network, older telephone numbers may be incomplete or incorrect. Since 1998, provincial codes, two or three digit codes beginning with 9, are obligatory even within regions. In April 1999 the first digit of mobile telephone numbers was changed to 6.
Electric current in Spain is 220 volts AC, 50 cycles. Most U.S. electrical equipment and appliances need a transformer and plug adapter.
