 "The semiformal Vuelta Abajo restaurant serves good Cuban cuisine, and there's a wonderful, shady little park just across the street" 
 "Despite its relatively small
size this place packs in several other charming
communal spaces, including a fantastic cellar-style
restaurant and a courtyard heaving with plants" 
 "The restaurant, Vuelta Abajo, specializes in country cooking from Pinar del Río and Viñales" 
 "For a bit more money, Hotel Ambos Mundos offers more sophistication and a stunning rooftop restaurant"
