Copenhagen is the capital and largest city of Denmark. This "friendly old girl of a town" is big enough to be a metropolis with shopping, culture and nightlife par excellence, yet still small enough to be intimate, safe and easy to navigate. Overlooking the Øresund strait with Sweden just minutes away, it is a cultural and geographic link between mainland Europe and Scandinavia. This is where old fairy tales blend with flashy new architecture and world-class design; where warm jazz mixes with cold electronica from Copenhagen's basements. You'll feel you've seen it all in a day, but could keep on discovering more for months. Copenhagen is considered a very liveable place because of its cleanliness. It’s considered as one of the very environmentally friendly cities because its harbour can be swum in and about a third of the city’s people use bicycles as their means of transportation. In their downtown area, the places to visit and to be entertained at are the Tivoli gardens and the Town Hall Square. If you want the very cultural and scenic areas the places to see are the Marble church, the Rosenborg castle, and the Christiansborg.

Saint Petersburg is a city and a federal subject (a federal city) of Russia located on the Neva River at the head of the Gulf of Finland on the Baltic Sea. In Russian literature, informal documents and discourse, the word "Saint" is usually omitted, leaving "Petersburg". The city is often described as the most Westernized city of Russia, as well as its cultural capital. It is the northernmost city in the world with a population of over one million. The Historic Centre of Saint Petersburg and Related Groups of Monuments constitute a UNESCO World Heritage Site. The city is home to The Hermitage, one of the largest art museums in the world. A large number of foreign consulates, international corporations, banks, and businesses have offices in Saint Petersburg. Talking of churches, Church of the Savior on the Blood is said to be the most beautiful church in St. Petersburg. Built of beautiful mosaic and stonework, the church gives you an indication of how ancient Russia looked like. The church is built at an equally historic spot. This is where Tsar Alexander II was assassinated in the year 1881.

Gdańsk (Danzig in German) is a port city on the Baltic coast of Poland. Gdańsk is situated at the mouth of the Motlawa River, connected to the Leniwka, a branch in the delta of the nearby Vistula River, whose waterway system supplies 60% of the area of Poland and connects Gdańsk to the national capital in Warsaw. This gives the city a unique advantage as the focus of Poland's sea trade. Together with the nearby port of Gdynia, Gdańsk is also an important industrial centre. Historically an important seaport and shipbuilding centre, Gdańsk was a member of the Hanseatic League. At the center of its Main Town, reconstructed after WWII, are the colorful facades of the Long Market, now home to shops and restaurants. 

Helsinki is the capital and largest city in Finland. Finland's major political, educational, financial, cultural, and research center as well as one of northern Europe's major cities, Helsinki was ranked the most liveable city in the world, in 2011. Approximately 75% of foreign companies operating in Finland have settled in the Helsinki region. The nearby municipality of Vantaa is the location of Helsinki Airport, with frequent service to various destinations in Europe and Asia. Today, Helsinki pulls off the trick of being something of an international metropolis while still retaining a small-town feel. The best time to visit is in summer, when Finns peel off their overcoats and flock to outdoor bars and cafes to enjoy the sunshine.
