First opened in 1966, this brash concrete-and-steel cube of a building seems decidedly at odds with its belle-epoque surroundings. Ugly from the outside it may be, but once you get inside the advantages of modern functionalism soon become apparent. All the rooms get a balcony with sweeping views, and the social areas at ground-floor level have an expansive, open-plan feel. Trendy modern artists decorated various parts of the hotel – look out for the Zvonko Lončarić sea-creature mosaic overlooking the indoor swimming pool. The newly-opened wellness centre in the basement offers state-of-the-art massage, aromatherapy and chocolate-bath facilities, alongside saunas, steam baths and whirlpools. Prices are per room and are subject to change.
