If you've ever been to Madrid, you'll know what a beautiful city it is. If you've never been to Madrid before, this guide will help you discover just how beautiful it is.

The Madrid DK Eyewitness Top Ten Travel Guide is a Palm-based version of the popular Dorling Kindersley series of the same name. The difference is, you get all the information from your PDA instead of having to carry a book around with the rest of your travel gear.

The guide contains a series of useful sections, all available from one handy - if not a little bland - interface. Among the area's to explore are Madrid's Highlights, Around Town, Streetsmart (a guide to staying safe outside in the city), plus a selection of zoomable maps and public transport guides.

By far my most favorite section, and the most unique of this particular guide is 'Madrid's Top Ten'. This contains a series of 'best lists' to help you prioritize the things you're going to see and do while you're in the city, from shopping, to sight-seeing, to night-clubbing.

The only thing I'd point out is that some of the prices listed for things like transport and food may become out of date fairly quickly, given the state of the economy today, but budgeting is really a concern you could always check online before you go.

If you want a well-written and refreshing guide to this wonderful Spanish city, the DK Eyewitness Top Ten guide makes for a useful mobile companion.
