Love a guarantee of luxury? Travelers to Prague, Perth and Paris can add several new hotels to their must-visit list, now officially recognized by Small Luxury Hotels of the World. In Perth, the 48 rooms of Como the Treasury make the most of the stunning, 19th-century state building that reopened at the end of 2015. Four floors have been restored to their original splendor, with the expansive Shambala Spa and two restaurants — Post, serving modern Australian bistro fare, and French-inspired Wildflower, where Executive Chef Jed Gerrard created a menu of European dishes built on Perth’s six indigenous seasons.

In Prague, the new Boho Hotel offers a city sanctuary in a space that once served as Prague’s post office. Now, 57 rooms have been created within, along with a fitness area, restaurant and a swish, contemporary spa with a steam bath and sauna. The Grand Hotel du Palais Royal in Paris enjoys a spectacular position between the Royal Garden and the Louvre. Here, fine dining and a menu of Champagnes at Le Lulli are served within a gorgeous space designed to resemble a winter garden, and spa offerings include Turkish baths and a menu of therapies. Elsewhere, a penthouse with wide views from its terrace takes in the Montmartre, Louvre and the Eiffel Tower.
