Miklošičeva cesta 1, 1000 Ljubljana, Slovenia

Grand Hotel Union, renowned as the most prestigious hotel of the time, had 120 rooms, several lounges and restaurants, a wine cellar, electric lighting, telephone, central heating, and a car garage. Guests then also had at their disposal so-called 'writing room' in which they could use a typewriter, and on Sundays, male guests could also afford a barber. All of the above was a real rarity exactly 115 years ago. And if it attracted attention then because of its grandeur, visitors today adore it for its distinctive Art Nouveau style, and the many carefully crafted details that connect the Baroque part of the city with more modern, Art Nouveau buildings.
