From the editors of Condé Nast Traveler:

At the end of the nineteenth century, the pretty resort town of Opatija, with its elegant parks and cafés, drew a titled crowd from all corners of the Austro-Hungarian Empire, but the music stopped with the outbreak of World War I. Now Opatija is staging a comeback, evidenced by the influx of stylish young European visitors. They're flocking to the Astoria Design Hotel, a Belle Epoque beauty that's been shrewdly renovated to offer good-looking comfort for reasonable prices. All 51 rooms are spacious and are kitted out in quiet colors and contemporary furniture. Many have small balconies, and all include flat-screen TVs. The slick lobby bar is popular with locals, and the restaurant has an excellent catch-of-the-day menu. —2006 Hot List
