Navigating Spain's vibrant cities and tourist spots is easier with a card in hand. Whether you're admiring art in Madrid or wandering through Barcelona's Gothic Quarter, cashless is the way to go. That said, keep some euros handy for those charming old-world transactions in bustling markets or at street-side stands. It's about finding that sweet balance between the convenience of modern payments and the authenticity of cash transactions in less touristy spots.
