Three days covers Madrid; a fourth is for Toledo

Lunch from about 2pm, dinner from 9pm; 7pm means tourist tables

The Prado, Reina Sofía and Thyssen sit 15 minutes' walk apart

Look in at San Miguel market, then eat in La Latina for less

Retiro's Crystal Palace is glass and iron, and free to enter

The Templo de Debod faces west: arrive 20 minutes early for sunset

Toledo or Segovia: pick one, each needs a full day
