All of the major tour companies serving Europe are British owned (Trafalgar, Insight, Globus, etc). The Brits know international travel, and when they do, they use Cadogan. This recently updated edition is a must have if you are going to Spain. Cadogan also publishes regional guides if you want even more detailed information. It is filled with more cultural and historical discussion than you will find in the "mass market" type guides like Fodors or Frommers. Clearly, the intelligent traveller's choice. The site, hotel, and restaurant recommendations are spot on, heed them. Five stars with no reservations whatsoever.
