Step inside the grand suites on the world's most famous train, which start at $26,000 a night and come with around-the-clock butler service

Guests are welcomed on red carpets for an overnight journey with lavishly decorated vintage carriages, fine dining restaurants, and jaw-dropping views of passing scenery.

Grand suites are the third tier of accommodation — one step above a suite and two steps above a historic cabin.

Each grand suite is inspired by a city on the train's routes, including Venice, Vienna, Istanbul, Budapest, and Prague.

They all include a couch, a double bed that can be converted into two twins, a dining area, and a full en-suite bathroom.

Each bathroom has a glass-blown sink, heated marble flooring, and a rainfall showerhead.

Grand-suite guests also get complimentary bathrobes and slippers.

Next to each bathroom is a closet with additional storage space so guests can fully unpack and feel at home.

Grand-suite guests are greeted with caviar upon arrival and can dine in their rooms rather than in the restaurant cars if they prefer.

They also get 24-hour butler service and bottomless champagne for the entire journey, the cabin steward told BI.

Venetian furniture, vintage glass light fixtures, and a combination of silk and woven fabrics fill this suite with a historic Italian ambiance. Navy-blue velvets are reminiscent of the train's exterior.

The headboard combining arches and sharp edges may remind one of the Renaissance castles in Italy.

The suite has a classic feel with dark wood contrasting gold trimmings.

According to a Belmond fact sheet obtained by BI, the headboard backing is made of silk to evoke a sense of elegance. Its curved shape and the tassel detailing in the bed's skirt may remind travelers of the historic city's regal palaces.

Shiny, hand-carved wood from the furniture to the walls is a work of art. For those who have been to the Turkish city of Istanbul, the embossed leather and fabric embroiderings may bring back memories of the city's opulent offerings at the famous and historic Grand Bazaar market.

The Budapest suite is decorated with ornate marquetry and furniture with embroidered silk patterns. The tall, curved headboard may remind travelers of Gothic cathedrals and mosques that date back to the Ottoman Empire.

Inspired by the city's architecture, the Paris suite nods to art deco elements, classical facades, and the city's high-fashion reputation with a geometric headboard and detailed wooden marquetry.

Maroon and gold are the colors of the Prague suite to bring travelers a sense of the city's theater scene. Mosaic patterns inspired by cubism fill the walls, and cushions embroidered by hand add luxury details to the furniture.
