Miramar is the most elegant part of Havana – as it was before the revolution, when the city’s richest inhabitants lived here. Life in this quarter revolves around the Avenida 5, a broad, tree-lined avenue flanked by splendid early 20th-century villas that are now home to embassies and institutions. On a walk through the quarter, you’ll pass these imposing mansions, as well as eclectic churches, fascinating museums and lively stretches of beach.
