“Rio is a beauty. But São Paulo, São Paulo is a city,” said Marlene Dietrich about Brazil's most cosmopolitan city. São Paulo is Brazil’s cultural as well as financial powerhouse, complete with a vibrant music scene, top-designer shopping, and delicious gastronomy, not to mention world-class museums and art galleries. All this is combined with the vibrant local life of Paulistanos, who will surely be easy to make friends with.

Cartagena de Indias reigns as the crown jewel of Colombia’s Caribbean coast — not for checklist attractions, but for its sheer atmospheric magic. Within its 16th-century stone walls (built to repel pirates like Sir Francis Drake), the city unfurls as a living postcard: pastel-hued colonial buildings, salsa rhythms spilling onto cobbled streets, and horse-drawn carriages clattering past vibrant plazas. By day, the scent of fried plantains and coconut rice fills the air; by night, rooftop bars hum with rum cocktails and sea breezes.

"The city in its setting and entire surroundings may be said to have something ideal." (Johann Wolfgang von Goethe, 1797). Scarcely any other European city has had its praises so often sung as Heidelberg. The mysterious Heidelberg Castle, the picturesque Old Town, and as Goethe himself stated, the perfection of its setting – in the nineteenth century, all of this attracted the German romanticists, who immortalized Heidelberg in poetry, music, and art. Today the charm of Old Heidelberg is combined with a future-oriented and international focus.
