With a pair of palace hotels leading the way, Europe delivers a king's ransom of notable debuts this season. The Four Seasons Hotel Gresham Palace Budapest (5-6 Roosevelt Tér.; 36-1/268-6000;; doubles from $335), an Art Nouveau gem with winter gardens near the Chain Bridge, recently opened after a $110 million restoration. • Well located in Barcelona's Gothic quarter, the Neri H&R (5 Sant Sever; 800/337-4685;; doubles from $189) is a cutting-edge boutique property in an 18th-century palace. • Named for its fashionable surrounding neighborhood, Lisbon's Bairro Alto (8 Largo Luis de Camoes; 888/452-8380;; doubles from $371) has made a splash with 55 warmth-infused rooms and suites revamped by the very stylish Grace Léo-Andrieu. • Owner and designer Kit Kemp, who created the Knightsbridge Hotel brings low-key comfort to London's West End with the 85-room Soho Hotel (4 Richmond Mews; 44-207/559-3000;; doubles from $433). • And taking the term cosmopolitan to its extreme, St.-Tropez's La Tartane (Rte. des Salins; 33-4/94-97-21-23;; doubles from $285) borrows from every corner of the globe: it has African-themed rooms and an authentic hammam.
