Where in Spain?

I've been to Madrid, Seville, Granada, Almería and Barcelona. I desperately wanted to go to Cádiz, San Sebastián and Valencia on that trip, but time constraints and full trains made it impossible. Next trip I plan to hit all of the places I didn't see the last time, spend more time in Seville (my favorite place in the world!) and check out Palma, Mallorca and Ibiza. Pretty well the only place I was largely unimpressed with was Madrid. It was a nice enough city, but difficult to navigate and not nearly as beautiful as Andalucía or Catalonia. God, I love that country, though. Have you been?
