The house
Mercer HotelesRestored palace sanctum
Sunlight filters across the arcaded patio, creating an oasis where guests gather quietly beneath original arches and contemporary chandeliers.
What it’s good at
Remarkable
Cruz y Ortiz restored the 1880 palace around a glass-domed courtyard with contemporary furnishings and bespoke lighting.
Notable
Twelve rooms receive personalized care with handwritten weather cards at evening turndown and high-tech Japanese toilets.
Notable
The 1880 Casa Palacio Castelar preserves its original neoclassical facade, soaring ceilings, and sweeping marble spiral staircase.
What they say
Also in Michelin and Condé Nast Traveler.
Design fans will immediately notice some truly inspired modern furniture, in both the lobby and the rooms — the contrast between the 19th-century architecture and the 21st-century design is lively, though subtle.
Right in the middle
Well-located: walkable to some things, a short ride to more.
Tucked away along quiet Calle Castelar in El Arenal, the stay is steps from the Guadalquivir riverbank and lively tapas bars.
The rooms
Soaring four-meter ceilings frame pale gray interiors, finished with contemporary Italian furnishings and spa bathrooms featuring Japanese toilets.
The rooftop pool
Bring a swimsuit.
A stainless-steel plunge pool sits on the sun deck, looking out over the terracotta rooftops of El Arenal.
At the table
María Luisa serves Andalusian dishes beside a vertical garden, and FIZZ Bar mixes cocktails developed with Diego Cabrera.
Spanish boutique hotel group Mercer—specialists in remodeling historic buildings into smart accommodations—converted this late 19th-century mansion in the El Arenal neighborhood into a polished, elegant five-star hotel in 2016.
How it began

Built in 1880 as the Casa Palacio Castelar, the neoclassical palace served as a nobleman residence before its 2016 transformation.
