About Madrid
Madrid is Spain's party capital where dinner starts at 10 PM and nightlife peaks at 3 AM. The Prado and Reina Sofía museums punch above Paris for art, tapas in La Latina are dirt cheap, and Retiro Park is where the whole city hangs out on Sundays. It's Madrid, not Barcelona — gritty, real, unpretentious.
- •Prado Museum (go Sunday evening when it's free)
- •Tapas crawl in La Latina or Malasaña neighborhoods
- •Retiro Park on Sunday afternoons
- •Rooftop bars in Gran Vía area for sunset
