Internet access

Most public libraries offer internet access, and there are many Wi-Fi hotspots throughout the city. In addition, if you have a wireless laptop or PDA, many cafés and restaurants now offer wireless internet access for little or no fee. The United Nations Secretariat building also offers wireless connectivity: search for the UNHQ-GUEST network name (no password required). One of the most reliable networks is offered by the coffee chain Starbucks, which has outlets conveniently located all over the city.


The US electric current is 110V to 115V, 60Hz AC. Outlets are made for flat two-prong plugs (which often have a third, rounded prong for grounding). If your appliance is made for another electrical system (e.g. 220V), you will need a step-down converter, which can be bought at hardware stores and drugstores. Most electronic devices (laptops, camera-battery chargers etc.) are built for dual-voltage use, however, and will only need a plug adapter.

New York City in brief

New York City is composed of five boroughs. While Manhattan and Staten Island are islands, Brooklyn and Queens are geographically part of Long Island, and the Bronx is attached to the US mainland. The islands are linked by bridges, tunnels and ferries. Check here for helpful NYC maps and guides.

Manhattan is 13.4 miles long and 2.3 miles wide at its widest. Except at its northern and southern tips, the borough's avenues run roughly north and south, and streets run east and west. One-way thoroughfares are common, with traffic moving east on even-numbered streets and west on odd-numbered streets. Fifth Avenue divides the island into east and west sides (for example, locations on 57th Street west of Fifth Avenue are designated "W. 57th St." and east of Fifth Avenue, they're "E. 57th St."). As you move farther east or west from Fifth Avenue, street addresses increase, usually in increments of 100 from one block to the next. For north-south avenues, 20 blocks equals a mile, and the street numbers increase as you go uptown. Blocks can be a useful measure of distance, but keep in mind your direction: walking uptown from 1st Street to 6th Street is about a quarter of a mile, but walking the same number of blocks crosstown, from First Avenue to Sixth Avenue, is approximately a mile.
