Concierge "The marble fitted bathrooms are also spacious, and those in the suites come with a hydromassage tub and separate shower"
Fodor's "The Meliá is filled with contemporary art and a collection of Spanish ship models, including miniaturized versions of vessels constructed in the city's historic shipyards"
