Grand Hotel Union Eurostars

Rooms and decor

Picture a six-storey cream Art Nouveau building tucked behind Ljubljana's iconic pink Franciscan Church — that's Grand Hotel Union, which first opened its doors in 1905. It was designed by Josip Vancaš, an Austrian-Slovenian architect who left his mark all over the city, and before the world wars it was the largest and grandest hotel in Yugoslav territory, hosting artists, writers, and diplomats from across Central Europe. It now runs under the Eurostars brand after a major renovation wrapped in 2024, but the originals survive — the facade, the wrought-iron balconies, the curving Vienna Secession lines, and the one thing every guest stops for: the mosaic staircase in the lobby, its pastel Art Nouveau floral pattern still glowing as if on opening day. Standard rooms in the old wing run compact, since restoring a historic shell means respecting the original layout; a Junior Suite or a renovated Business-wing room gives you more space.

Food and amenities

The heart of the building is the Unionska Dvorana, the original ballroom from the founding era — high vaulted ceiling, a giant crystal chandelier, gilded plasterwork around the edges — used for classical dances, piano evenings, and concerts for well over a century. Next door, the Smrekarjeva dvorana, where painter Hinko Smrekar left murals on Slovenian themes, serves a buffet breakfast that reviews agree is fuller than expected: Prosciutto Kraški, the smoked ham wind-cured in the Karst hills, strong local cheeses, fresh-baked pastries, seasonal fruit, and good coffee. The new headline everyone mentions is the top-floor wellness spa with an infinity pool that reopened after the 2024 work — step in, face southeast, and Ljubljana Castle stands full in view on its hill. At sunset, when the castle lights up, reviews call it the best hour of the stay. There's a Finnish sauna, a steam room, and a roof deck too. Down in the lobby, Café Union has served coffee to locals since before the world wars.

Location and getting there

For location, Grand Hotel Union is the definition of walk-to-everything central Ljubljana. It sits on Miklošičeva cesta, a street lined with Art Nouveau buildings. Turn left out the door and 3 minutes gets you to Prešeren Square, the heart of the city, with the pink Franciscan Church that's Ljubljana's postcard. Cross the bridge another 30 seconds on and you reach the Triple Bridge (Tromostovje), Jože Plečnik's three-way masterpiece into the Old Town south of the Ljubljanica river. The Central Market and riverside restaurants are just along the bank, and it's about 15 minutes uphill to Ljubljana Castle. The central train and bus stations are only a 5-minute walk — arrive by train from Vienna, Zagreb, or Venice and you can wheel your bag straight to check-in. From Brnik airport, around 25 km out, it's a 25-minute bus or taxi. Stay here and you barely pay for transport all trip; every landmark sits within a 10-minute walk.

Things to know before booking

Straight talk to help you decide. The most common gripe is street noise from Miklošičeva — some old-wing rooms facing the main street pick up trams, foot traffic, and bars at night, loudest on Friday and Saturday when the city is busy. Light sleepers should ask for a courtyard-side or higher-floor room up front. The second is room size: standard old-wing rooms are compact for a 5-star, a trade-off of restoring a historic building, so move up to a Junior Suite or a renovated Business-wing room if you want space and a separate sofa. The third is the elevators — the old building has only a few and they aren't large, so a busy checkout morning can mean a 5–10 minute wait. A few reviews also note the temperature controls lag between seasons, in early spring and autumn, so a room can run too warm or cold for a day before the central system catches up. One small thing: Wi-Fi is weaker on the lowest floors, so for an online meeting ask for floor 3 or above.

Our take

After reading through real guest reviews and the history of this building, Grand Hotel Union Eurostars is the best answer for anyone who wants to sleep inside Ljubljana's legend without giving up location or modern comfort. A 1905 Art Nouveau building freshly restored in 2024, a dead-central spot within a 5-minute walk of every landmark, a new rooftop pool and spa facing the castle, plus a real ballroom and mosaic staircase — together that's a package you won't find elsewhere in this city. It suits couples, classic-minded travelers, and business guests who want to be near both the station and the Old Town. If the heart of your trip is soaking up Central European history from inside a building that's still alive, this is the top pick. If you'd rather have a big new minimalist room, the old-building charm here may not be what you're after. Overall we give it 8.9/10 — a score worthy of staying in one of Ljubljana's institutions, the kind of place you wake up wanting to walk down that mosaic staircase one more time before checkout.
