Rooms are spacious and bright with plush bedding, iPod docks, and attractive vine-draped balconies.

Additional perks include Nespresso machines, free Wi-Fi, and a free organic buffet breakfast.

This charming, upscale boutique feels like a private home, with 11 beautiful, individually decorated rooms featuring hardwood floors, comfortable beds, and great amenities. Each room has been dedicated to a significant figure in Argentine history -- such as Evita Peron, Che Guevara, General San Martin and Mafalda -- and has themed decor to match. The cozy library is the perfect place to unwind after a long day of sightseeing in the winter, and in the warmer months guests can head up to the rooftop deck, complete with a six-person whirlpool and lounge chairs. There’s an attractive breakfast room with classy, homey decor, in which a decent breakfast is served every morning. There’s no full restaurant on-site, but the hotel’s excellent location in the heart of vibrant Palermo Soho offers easy access to plenty of great restaurants. It's gorgeous, unique style and intimate atmosphere put it toward the top of our list.

Opened in early 2011, this beautiful boutique hotel is arguably one of the most special and serene properties in bohemian Palermo Hollywood. With just 12 rooms and simple but stylish modern decor throughout, it is a wonderful retreat from busy Buenos Aires, even with a location in the thick of the action. Large, sun-drenched rooms are clean and contemporary, with flat-screen TVs, floor-to-ceiling windows, trendy bathrooms with jetted tubs (one of the reasons this gets a higher spot on our list), and a few colorful accents. The gorgeous rooftop whirlpools with city views and a sauna help make it particularly romantic. Book a room facing the tiny back garden for quieter weekend nights.

On an attractive, tree-lined street in the La Recoleta neighborhood, the CasaSur Art Hotel is a luxe, boutique property with 36 rooms. Decor is sleek with modern furniture and dark hardwood floors. Comfortable rooms have thoughtful touches of technology, including iPod docks and wall-mounted flat-screen TVs. While bathrooms are relatively small, they are sophisticated with marble vanities and glass walk-in showers. The highlight of CasaSur is an upscale spa complete with whirlpool, and the hotel also offers its own restaurant serving food inspired by India and the Mediterranean. Its desirable location and big rooms with balconies make it one of our favorite romantic picks; the on-site spa gives it a slight edge over the Glu Hotel.

The Glu Hotel, a small, boutique property in the posh Palermo neighborhood, feels like an urban oasis in bustling Buenos Aires. The rooms are spacious, stylish, and clean with a clever layout that somehow offers multiple seating options, a workspace, a living/lounge area, and a king-size bed, and still leaves room for morning yoga on the hardwood floors. The rooms also come complete with balconies and smart extras such as dishes, wine glasses, cutlery, a microwave, and convenient bar seating for romantic in-room meals. The lobby bar and patio are chic spots to enjoy an evening cocktail, or guests can really unwind after a day of sightseeing with an in-room massage treatment. The huge rooms and attentive staff make it a great pick for couples.
