Moscow is a city of contrasts where the bohemian and the glamorous merge in an idiosyncratic fusion – do not be surprised to find a golden-domed 16th-century church next to an ultra-modern glass skyscraper or a Soviet blockhouse. Here, salty fish eggs (caviar) are washed down with bubbly champagne, and worn-out commuters travel by the elaborately decorated, elegant metro, one of the city's main attractions.

Unjustly overlooked by travellers en route to Tunisia's celebrated seaside resorts, the nation's capital certainly deserves more than just a quick glance through the shuttle bus window. The city lives and breathes history, from the crumbling columns of Carthage to Medina's labyrinthine alleys, where the scent of orange blossom mingles with freshly baked tabouna bread. This is where Roman mosaics, Ottoman arches and mid-century modernism collide with unshowy authenticity.

The majestic Faisal Mosque stands against the backdrop of the lush Margalla Hills as a symbol of a Pakistan placed firmly in the modern day, while holding on to its history and traditions. The capital city of Islamabad is a forward-thinking metropolis nestled in the green Himalayas. Usually regarded as a diplomatic city, it has become an important business and financial centre for the region, as well as an emerging travel destination. Together with its neighbouring sister city of Rawalpindi, Islamabad gives travellers in-the-know a taste of contemporary Pakistan.

Anything you can dream of you will find in the Polish capital: interesting history, a wealth of events, exciting nightlife, Michelin-starred restaurants, and an abundance of green areas. Check out the charming Old Town and take a stroll down the Royal Route. Learn about the city's history in one of Warsaw's many interactive museums. Spend a wild evening by the Vistula and chill out listening to a Chopin concert at Łazienki Royal Park. No doubt, Warsaw is a must-see on the tourist map of Europe.

Santander is famous for its fabulous beaches and its elegant holidaymakers: King Alfonso XIII used to spend his summers here nearly a hundred years ago, and the town is still popular among fashionable madrileños who like to be seen sauntering along the El Sardinero seafront with its belle époque architecture. When the sun goes down, the town is busy, with great restaurants and a lively bar scene. It is also a good place from which to explore the pristine countryside of Cantabria.
