Mercer Madrid
Madrid, Spain · Mercer Hoteles · Accessible Luxury
The Sociedad General Azucarera de España built its headquarters on Ruiz de Alarcón in 1905, a company formed to hold the Spanish beet-sugar industry together after Spain lost its last colonies and the Cuban cane with them. The architect was Enrique María Repullés y Vargas of the royal household, who had already built the Stock Exchange that the windows look out at. Mercer opened 61 rooms in it in 2026 behind Andreu Carulla's interiors, with Eneko Atxa cooking at La Sociedad Gastronomika and a pool on the roof.

About Mercer Madrid
- Eneko Atxa, who holds three Michelin stars at Azurmendi outside Bilbao, named his restaurant here La Sociedad Gastronomika after the sugar company. The cocktail bar is a Dry Martini by Javier de las Muelas.
- The house keeps one of the oldest working lifts in Madrid, restored along with the original wooden carpentry, staircases and roof in concert with the state heritage directorate.
- Andreu Carulla calls his room design silent engineering: a bespoke wooden shelf wall in each room folds away a minibar, a dressing mirror or a desk, and the bathrooms are cut from Rosavel granite.
- The 91 square metre Mercer Suite on the fifth floor opens onto a 34 square metre private terrace with a plunge pool above Ruiz de Alarcón.
- The opening landed on Mercer Hoteles' twentieth anniversary and made Madrid the group's eighth house in Spain, after Barcelona, the wine town of Vilafranca del Penedès and Seville.
History
The building at Ruiz de Alarcón 5 was designed in 1905 by Enrique María Repullés y Vargas, architect to the Spanish royal household and the man behind Madrid's Stock Exchange palace a block away, as the corporate headquarters of the Sociedad General Azucarera de España. That company had been assembled to gather and represent the national beet-sugar industry after Spain lost its last colonies, and with them the Cuban cane that had fed the Spanish sugar trade. Repullés gave the sugar men a house that mixes neoclassical composition with neo-Mudéjar brickwork, and it carries Level One heritage protection in Madrid's catalogue of protected buildings.
Mercer Hoteles took the 5,548 square metre building and reopened it in spring 2026 as its first hotel in the capital and its eighth in Spain, the opening timed to the group's twentieth anniversary. RCCyP Arquitectura led the architectural work and Andreu Carulla Studio the interiors, and the original wooden carpentry, staircases and roof were restored in collaboration with the state heritage directorate. One of the oldest lifts in Madrid still runs inside.
There are 61 rooms and suites over five floors in six categories, with high ceilings, theatrical original mouldings, balconies over Los Jerónimos and free-standing tubs in bathrooms cut from Rosavel granite. Carulla built each room around a different modular wooden shelf wall that hides the minibar, a dressing mirror or a desk, an approach he describes as silent engineering. The 91 square metre Mercer Suite on the fifth floor has a 34 square metre terrace with a plunge pool. Downstairs, the three-star Basque chef Eneko Atxa runs La Sociedad Gastronomika and Javier de las Muelas keeps a Dry Martini bar; above, a rooftop carries a pool, a solarium and a bar over the centre of Madrid.
The setting
Los Jerónimos is the quiet stately quarter behind the city hall, between the Paseo del Prado and the Retiro, and it is about as central as Madrid gets without the noise. The hotel looks across at the Madrid Stock Exchange. The Prado is a two-minute walk, the Thyssen-Bornemisza and the Reina Sofía complete the Art Triangle a little further along the Paseo, and Cibeles and the Puerta de Alcalá stand at either end of the neighbourhood. The Retiro gates are at the top of the street.
