Stockholm - Sweden's capital and largest city, and the most populous city in the Nordic region. Without a doubt, Stockholm is one of the most beautiful cities in Europe. The city is made up of 14 islands connected by some 50 bridges on Lake Mälaren, which flows into the brackish Baltic Sea, and passes the Stockholm archipelago with some 24,000 islands and islets. The city is a cosmopolitan place with both classical and modern architecture, and a captivating Old Town, Gamla Stan. Today, the area is an atmospheric mixture of buildings surrounded on all sides by a latticework of medieval lanes and alleyways.

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.
