Grand Hotel Union, Ljubljana, Slovenia $$$$
Concierge.com's insider take:
This magnificent Art Nouveau building dates back to 1905 and takes up two-thirds of a city block about 150 feet from the central Prešernov Square and the Triple Bridge. It has been substantially refurbished in the past decade, and although the interiors have a business-hotel anonymity, the bedrooms are spacious, light, and comfortable with slick granite bathrooms. Be sure to ask for a room in the "executive" wing, not the dreary 1960s annex dubbed "business" (the latter has a separate address and phone number).
