This grand Secessionist mansion, the Schlessinger Palace, houses Zagreb‘s first hotel, opened in 1907. More than a century later, it’s still one of the city’s most elegant properties. All 120 rooms – and three suites – are a mix of Art-Nouveau decor and contemporary amenities: sturdy dark-wood furniture, huge windows, original paintings and spacious bathrooms with tubs. For minimum noise and the best views of Sljeme, book a courtyard-facing room. The ground-floor café is decorated with fantastic Habsburg-era frescoes and serves up excellent cheese štrukli.
