All eyes are on the Dutch capital, thanks to its booming hotel scene. Spread across three 17th-century merchant’s residences on the Keizersgracht, Canal House (doubles from $346) made its debut in April, with modern Dutch paintings in its 23 monochromatic rooms. Sofitel’s The Grand (doubles from $346) just did a refit, adding a bi-level So Spa as well as a seafood-centric restaurant. Not to be outdone, Hotel de L’Europe (doubles from $490) has reemerged from a two-year renovation with 23 new suites featuring Rijksmuseum replicas. Next month, a century-old music conservatory will relaunch as the Conservatorium (doubles from $577), housing 128 Zen-like suites and a holistic spa. And in September, the owners of the city’s edgy Lloyd Hotel are slated to unveil the Exchange (doubles from $289), designed by Amsterdam Fashion Institute students.
