ブエノスアイレスのホテル ベスト10 2026年版 — レコレータ、パレルモ、プエルト・マデロ(ブルードル裏技で40〜60%節約、ステーキ・マルベック・タンゴの都)

Picture a 1934 French-style palace that the cattle-baron Duhau family commissioned architect Léon Dourge to model on a Loire Valley chateau, standing on Avenida Alvear, the most expensive street in Buenos Aires. That is the Palacio Duhau - Park Hyatt Buenos Aires, run under Park Hyatt since 2006 after a careful restoration by Hampton, Rivoira & Pflueger that kept the cream-marble staircase, stained glass and original fireplaces almost entirely intact. There are 165 rooms across two wings: the 23-room Palacio Wing in the original palace, and the 142-room Posadas Wing, many with balconies over the hidden garden that links the two buildings via an underground art tunnel. The headline draw is Duhau Restaurante & Vinoteca, with a 6,000-bottle Argentine cellar and a real cheese-ageing room, plus the 1,500-square-metre Ahin Spa and its 18-metre indoor pool. Rooms start around $630 a night, and reviewers have voted it the city's number-one hotel for nearly two decades.

The Alvear Palace Hotel has held down Avenida Alvear in the heart of Recoleta since 1932 — nearly a century of defining what old-money Buenos Aires looks like. The classic European facade was modeled on Paris in its golden age, and inside it commits fully: Louis XV and Louis XVI interiors, silk-lined walls, gilt furniture, and real Baccarat crystal chandeliers. A floor butler on every level handles the small stuff personally. There are 210 rooms and suites, many facing the famous Recoleta Cemetery or the leafy avenue. You get the Michelin-tier French restaurant La Bourgogne, an afternoon tea that lands in every South America guidebook, an L'Occitane spa, an indoor pool, and a full gym. The cemetery is a 5-minute walk, the Callao metro (Línea D) about 10, and Aeroparque airport roughly 15. It scores 9.2/10 and suits couples and classic-luxury travelers who care more about story and service than the latest design.

Four Seasons Hotel Buenos Aires pairs two buildings from different eras and makes it work. La Mansion, a Belle Epoque townhouse built in 1916 for the aristocratic Alzaga Unzue family, holds 7 French-classical suites you won't find anywhere else; a 13-storey modern tower added later carries the rest, for 138 rooms and suites total. It sits on Posadas street where Recoleta — the city's smartest district — meets Retiro, so the famous Recoleta Cemetery (where Eva Peron is buried) is about an 8-minute walk. Every review circles back to three things: the Roman-style rooftop pool ringed with columns and cabanas, the roughly 1,700-square-metre spa (one of the largest in town), and Elena, ranked among the best dry-aged steakhouses in Latin America. Guest average is 9.1/10. Best for couples and luxury travelers who fall for a building with a story.

Faena Hotel Buenos Aires is the dream project of Argentine businessman and art collector Alan Faena, who handed a century-old red-brick wheat silo on the Dique 2 canal in Puerto Madero to French design legend Philippe Starck. Built in 1902 and reopened as an 88-room hotel in 2004, it runs on a deep crimson-gold-white palette down a long velvet corridor everyone calls the Cathedral. The signatures stack up fast: a 35-metre outdoor pool set in a wooden garden, the Rojo Tango cabaret staged live nightly, the El Mercado parrilla grilling Argentine steak over charcoal, and a spa with a Turkish hammam. Rates run from roughly $485 to $1,315 a night. We land on 9.0/10 because real guest reviews agree on two things — a design no other hotel on earth copies, and butler-level service that pays attention.

Casa Lucia, Meliá Collection is one of Buenos Aires' freshest 5-star openings — Spain's Meliá took over the historic Mihanovich building from 1929 (most recently a Sofitel) and relaunched it in late 2024 in the central Retiro district, a 3-minute walk from Plaza San Martín. The draw is the period Art Deco design — gold and emerald-green tones, plaster moldings and mosaic floors that preserve the city's golden-age detail. The 142 rooms and suites feel more like an old Porteño apartment than a chain hotel, and a few on floors 5–7 have wrought-iron balconies over the square. The headline feature sits downstairs: a club bar with a working fireplace and a Malbec wine list that reviewers rank among the longest in town, plus an indoor pool and spa that are genuinely rare this central. Rates start around $360 a night; the 9.1/10 score suits couples and design-minded luxury travelers.

Mio Buenos Aires is a 5-star boutique of just 30 rooms tucked onto Quintana street in Recoleta, built by cousins of the Catena family, Argentina's biggest Malbec wine dynasty. The character starts at the front door — a 5.5-metre slab of oak reclaimed from Catena Zapata wine barrels — and carries into a lobby clad floor to ceiling in barrel wood, so the air smells like a Mendoza cellar before you've checked in. Every room runs warm oak and a big Carrara marble tub, the detail every review fixates on. Downstairs there's an indoor pool, a quiet spa, and a restaurant and wine bar that draws Malbec pilgrims for cellar-vintage Catena pours you won't find in city restaurants. The location is the close: 5 minutes' walk to the world-famous Recoleta Cemetery, a few blocks from the city's best cafes and museums. Overall 9.2/10 — a couples-and-wine-lovers stay with a real story behind it.

CasaSur Recoleta Hotel is a 35-room, 5-star boutique on Av. Callao between Quintana and Alvear, planted in the heart of Recoleta — the district locals compare to Paris's 16th. The four-storey building runs warm with wood and brass, and several rooms open onto small balconies over a street lined with palo borracho trees so dense they throw real shade. The standout is a full in-building spa, genuinely uncommon at this size, plus staff who greet you by name from the first check-in. It's an 8-minute walk to Recoleta Cemetery (where Eva Perón is buried) and the Floralis Genérica sculpture, 7 minutes to Callao station on Line D, and a 15-minute ride to the city airport, Aeroparque (AEP). Rates start around $185 a night — strong value against same-tier luxury hotels nearby. Overall 9.0/10, best for couples and luxury travelers who value location and service over a big glossy property.

Home Hotel Buenos Aires was the first boutique hotel in Palermo Hollywood, opened in 2005 by Argentine-British couple Patricia O'Shea and Tom Rixton, who turned a 1940s house into a design stay of 18 rooms and 2 suites. The heart of the place is the central flower garden with an outdoor pool ringed by wooden daybeds and canvas umbrellas — the corner guests claim for a full afternoon with a book. Decor blends industrial steelwork with mid-century furniture, and Patricia hand-picked vintage British wallpaper so no two rooms match. The lobby cocktail bar and cafe pull in the city's music and fashion crowd, especially on DJ nights. You're a 10-minute walk from the parrillas, cocktail bars and design shops that define the neighborhood. Rates start around $157 a night, the overall score is 9.1/10, and it suits couples and design-minded travelers who value atmosphere over big-chain polish.

Vain Boutique Hotel is an early-20th-century Porteño house in the heart of Palermo Soho, renovated into a 4-star boutique of just 15 rooms. It sits on Thames street, about 5 minutes' walk from Plaza Serrano (Plazoleta Cortázar), the square at the centre of the district, ringed by Argentine designer shops, well-known parrilla steakhouses, and cafes that stay open late. The detail every review agrees on is the rooftop — a small outdoor jacuzzi and a lounge corner for an evening glass of Malbec. Breakfast is served a la carte rather than buffet, a proper brunch of medialunas, eggs to order, and fresh orange juice. Staff speak fluent English and run the place with a neighbourly warmth. Rates start around $120 a night, a strong deal for the hippest address in Buenos Aires. Overall 8.9/10 — best for couples and walkers who want to soak up Palermo up close.

Patios de San Telmo is a 4-star boutique of about 32 rooms hidden behind a tall wooden door in the middle of San Telmo, the oldest neighbourhood in Buenos Aires and the real home of tango. The building started life in the 1850s as a conventillo, a shared tenement for the Italian and Spanish immigrants who poured into the city, and its careful restoration earned an architecture-conservation award, keeping the high ceilings, exposed brick, and original colonial floor tiles intact. Rooms ring four colonial patios planted with lemon and orange trees, little stone fountains, and wrought-iron chairs made for a morning mate. Up on the roof, a small pool and bar open onto the terracotta rooftops of the old quarter. It's a 6-minute walk to Mercado San Telmo, and every Sunday you step straight out into the Feria de San Telmo antiques fair. Overall 8.8/10 — a couples-and-culture stay with a 170-year-old story behind it.
