Harking back to the golden era when Panama was the gateway between Central and South America, as well as a meeting place for creatives and influencers from around the world, Atelier Ace's first independent addition to its family is the Colonial-style American Trade Hotel. Making itself at home in the Casco Viejo neighborhood of Panama City, the hotel occupies a 1917 neoclassical building that was originally Panama's first skyscraper but stood abandoned for many years.

Pack your espadrilles and fedora and you'll fit right in with the hotel's tropical ambience, complete with sweeping views of the surrounding neighborhood and its very own in-house jazz club.
Rooms from $249 to $799

Arriving at your hotel by boat might not be a big deal in Venice, but when your pied-à-terre is housed in the lavish 16th-century Palazzo Papadopoli, your travel companion will definitely be impressed.

Outlandish luxury at its best (think 18th-century Murano chandeliers), the new Aman Canal Grande features soaring ceilings, historic frescoes, and private gardens for enjoying the views of the Grand Canal, minus the hordes of tourists. If it rains, the library, dedicated card and jigsaw tables, and elegant chess and backgammon sets will keep you busy.
Rooms from $1,550 to $5,000

Standing tall in the swiftly gentrifying Istanbul neighborhood of Karaköy, in a building dating back to 1863 that was once a bank (its vaults now act as the hotel's expansive wine cellar), Vault Karaköy even staffs its own in-house art curator.

For stellar views of Istanbul's Bosphorus bridge, Old City, and the Golden Horn inlet—all from the comfort of your bathtub—book a Terrace Penthouse Suite. Or, if you're in need of a good scrubdown, the hotel's impressive spa offers Turkish-bath services.
Rooms from $260 to $340

As a lovesick teenager you may have mastered the art of sneaking into an all-girls school, but this time there's no need to climb through the window. One of Stockholm's most storied Art Nouveau buildings—formerly a girls school—is now the elegant boutique hotel Miss Clara.

The history of Providence's newest boutique lodging is both pious and sordid. Built in 1912 by the Episcopal Diocese of Rhode Island to serve as a rescue mission, the building was later a strip club and transient hotel before it became a longstanding adult-entertainment venue.

It's since shrugged off its seedy past and been reborn as a sleek, 52-room hotel adorned with stylish trappings that include vintage furniture, The Elder Statesman blankets, and custom-designed beds, desks, valets, and lighting by ASH NYC. You can also grab a cold-press coffee from Bolt Coffee Company in the lobby café or take a leisurely spin around downtown Providence on one of the hotel's restored vintage bicycles.
Rooms from $79 to $139

Designed and owned by architect Antonio Girardi, this 24-room hotel was once a 17th-century Claretian monastery in the heart of the aristocratic (and very cool) Via Giulia neighborhood in the city's historic center.

Velvet headboards, cashmere and silk carpeting, and mirrored televisions make the experience anything but monastic, but if you're after a few quiet moments of contemplation, head up to the private terrace for expansive views of the city's picturesque tile rooftops and bell towers.
Rooms starting from $325 (suite prices upon request)

Thanks in part to the opening of Mario Testino's new Lima art gallery, the historic bohemian neighborhood of Barranco has become one of the city's hippest haunts. The latest luxury dwelling to open its doors in the barrio is Hotel B, a revived Belle Époque mansion built in 1914 by renowned French architect Claude Sahut that served as a seaside retreat during the presidency of Augusto Leguia in the 1920s.

Claw-foot bathtubs, antique chandeliers, and 1920s-era furnishings will imbue your stay with old-world glamour, and you can indulge your penchant for art with the hotel's own unique collection or explore Lima's thriving gallery scene.
Rooms from $315 to $700

The Russians might have missed the mark with their accommodations at the Sochi Winter Olympics, but we're heartened to know that they still know how to do over-the-top luxury like pros. An 1820s palace designed for Princess Lobanova-Rostovskaya (which later became home to the Ministry of War) is now enjoying a modern incarnation as the latest addition to the Four Seasons family.

To really revel in palatial splendor, book the 1,636-square-foot Lobanov Presidential Suite, perched atop the hotel's heritage grand marble staircase. You'll have your own private terrace, a marble bathroom, and a dining area with a 10-seat mahogany dining table, in case you're expecting a guest—or nine.
Rooms from $450 to $14,500
