Here's a handy resource for travelers to San Juan: Areas Urban Guides provide downloadable maps, information, and business listings (restaurants, shops, spas, and other businesses that cater to tourists) for Old San Juan and Condado (Isla Verde is still under development).

Of course, this is by no means a complete listing, but it's got some good information that will help you get around the most popular tourist areas of the city. It also, happily, includes some of my favorite destinations in San Juan, like:

• Ajili Mójili for dining Puerto Rican dining.
• Nono Maldonado for high-end fashion.
• Trois Cent Onze, one of the best international restaurants on the island.
• Nuyorican Café, a cool, bohemian salsa joint that makes for a fun romantic evening.
