It is said that natives of Cologne who are living elsewhere always feel homesick, and visitors to this beautiful city will soon understand why. Germany’s oldest metropolis, which, of course, gave its name to the Eau de Cologne, offers a mix of magnificent and romantic churches, cutting-edge modern architecture, busy shopping streets, and world-famous museums. There is much to do and see in Cologne, and with all the frequent flights and transportation options, getting here has never been easier.

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.

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.

Graz – Austria’s culinary and cultural capital. A practical tip from the start: If you want to explore Graz, wear comfortable shoes and loose clothing. Why? Even if Graz is actually small — the second-largest city in Austria with a quarter of a million resident by no means a “big city” — you should be prepared for the fact that time also flies in the many short lanes. Comfortable footwear goes easy on busy feet here. In the historic old town with its roads, streets, squares and courtyards there’s lots to explore and even more to enjoy.

Limerick, located on the banks of the River Shannon, holds the distinction of being Ireland's first-ever City of Culture. The city, famously remembered as the setting for Frank McCourt's "Angela's Ashes", boasts a dynamic blend of art galleries amidst its charmingly decrepit Georgian architecture. Known for its strong rugby culture, Limerick also has a thriving street art community, a bustling festival calendar, and the Milk Market that serves as a hub for food lovers.
