When Valencia won the bid to host the 2007 America’s Cup, there wasn’t a single hotel on the waterfront near where the races are to be held. Since then, developers have scrambled to build ocean-side accommodations to suit the city’s new profile. One property has emerged from the frenzy as the clear standout: Hotel Neptuno. With its cool retro signage and rooftop Jacuzzi, Neptuno’s exterior is evocative of Modernist Miami. The inside, meanwhile, is pure Spain, with a dramatic glass elevator surrounded by a cascading waterfall and paintings by Valencian artists. Thirteen of the 47 rooms face the beach, and while they’re not the most spacious, they make the most of what they have, with rectangles of chocolate-colored wood serving as headboard, nightstand, and light fixtures.
