A 12-suite boutique in the restored 1880 Castelar Palace — the only Seville hotel with a rooftop pool and Cathedral-line-of-sight terrace, with the Calixto Mediterranean tasting menu and a 1:1 staff-to-suite ratio.
"Twelve suites. The 1880 Marqués de Sortes mansion. The only rooftop pool in central Seville and the only rooftop bar where the Giralda is at eye level. The smallest five-star booking in Andalusia, and one of the best."
The Mercer Sevilla occupies the Casa Palacio Castelar — an 1880 noble mansion built for the Marqueses de Sortes on Calle Castelar in the Arenal barrio, two blocks from the Cathedral and three from the Plaza de Toros de la Maestranza bullring. The building was acquired in 2015 by the Salas family — the Catalan hospitality family behind the Mercer Hotel Barcelona — and underwent a comprehensive three-year restoration to designs by Madrid architects Ortiz.León before opening as Mercer Sevilla in March 2018. The principal architectural decision was to preserve the original Andalusian central courtyard with the marble columns and the original tile work intact, and to extend the building upward with a contemporary glass-and-steel rooftop level housing the pool, bar, and the building's principal sun terrace.
The 12 suites — eleven Junior and Premium categories plus the named Royal Suite — are arranged across the original three floors with the 1880 plan preserved. The smallest unit is 35 square metres; the Royal Suite is 95 square metres with a private balcony directly overlooking Calle Castelar. The architectural quality of the rooms is the proposition — restored stuccoed ceilings, original 1880 parquet preserved, restored brass and tile fittings — and the hotel maintains a deliberate 24-staff-to-12-suite ratio for the service register. Bathrooms are travertine; bath products are Florència, Mercer's own brand.
Calixto is the headline restaurant in the original courtyard, with the marble columns and original tile work overhead — a Mediterranean tasting programme rooted in Andalusian preparations under chef Juanlu Fernández, the Cádiz-born chef who held a Michelin star at LÚ Cocina y Alma in Jerez and brought the same modernist register to Mercer in 2022. The Lobby Bar and the Library run the all-day cocktail programme. The headline image is the Castelar Rooftop — the only rooftop pool in central Seville's old quarter and the only rooftop bar where the Giralda's belfry stands at eye level — open evenings from 6 PM with an aperitivo and tapas programme through to midnight, and reservations only for non-residents.
The Calle Castelar position is the booking trade-off — a very quiet, residential block, two blocks from the Cathedral and the Maestranza bullring, and the El Arenal barrio of the Triana-bridge access. The Alfonso XIII is the heritage-grand-palace alternative; the Mercer is the small-and-architectural-and-rooftop alternative. For couples and small groups wanting the smallest, most-personalised five-star booking in Andalusia, this is unambiguous.
The Royal Suite, dinner at Calixto in the courtyard, the Castelar rooftop pool through the afternoon, and the 1:1 staff-to-suite ratio that means every request is handled by a named butler. The smallest, most-personalised honeymoon booking in Andalusia.
The Castelar rooftop at sunset with the Giralda at eye level — the most-photographed proposal terrace in Seville and the staff's signature set-up. The hotel handles ring delivery, photographer arrangement, and the post-proposal Calixto dinner programme as a single coordinated booking.
A milestone-anniversary booking that prioritises personalisation over heritage scale — book the Royal Suite, the rooftop dinner-for-two booked privately on the Castelar terrace, and the staff team handles the rest. The right Seville anniversary booking for the second-visit traveller.
