Most tourist sites are within the city centre, which is easy to navigate on foot. However, Athens has an extensive public transport network consisting of buses, trolley buses, trams and a fast, three-line underground metro service. The metro and the tram network are especially useful for tourists. Transport is cheap, but often overcrowded, especially during rush hour (1-3pm). Most public transport operates until midnight, with a limited night bus and tram service operating along major routes. Although taxis are plentiful, it may be difficult to get one during rush hour. For this reason, it's not unusual to share the ride with other passengers. Taxis are inexpensive, but visitors should always check that the meter is on and set to the minimum fare. Drivers often attempt to overcharge tourists. Legitimate surcharges can increase the final bill, but these should be displayed on the dashboard.
Electrical current is 220 volts and 50Hz. A variety of plugs are in use, including the European-style two-pin and the round three-pin.
The official currency is the Euro (EUR), which is divided into 100 cents. Banks and bureaux de change are widely available and major credit cards are accepted. ATMs are widespread and are generally the cheapest and most convenient method of obtaining euros.
The international access code for Greece is +30. The outgoing code is 00 followed by the relevant country code (e.g. 0044 for the United Kingdom). The city code for Athens is 21. Free wifi is available at cafes, restaurants, hotels and other similar establishments throughout Greece. As international roaming costs can be high, purchasing a local prepaid SIM card can be a cheaper option.
