Can you really fit in everything in Madrid—glittering palaces, bustling squares, and markets piled high with delectable dishes—in just 24 hours? As someone who’s explored every nook and cranny of Spain’s dazzling capital city, I can guarantee you that a day is enough to take in all of the must-see sights. On top of that, you’ll be able to fit in a fabulous flamenco show in the evening. Sure, you’ll wish you had more time to try even more tapas or to say yes to another glass of wine, but that would be the case even if you spent a year here.
