Things to Do
The most important sights are clustered in the Centro (the old city) so walking that route is Madrid’s main attraction, from the Royal Palace at the west end to the incredible Post Office at the east.
On the way between them visitors will stumble upon many and varied plazas that will offer refreshments and sights.
Oddest great sights: the most magnificent Post Office ever (Plaza Cibeles), the strangest train station waiting room (Atocha’s tropical forest).
Madrid’s best green relief is Parque del Retiro.
And don’t forget to try some of the little tiled bars where Carmen awaits you, possibly.
