A friend, who is lucky enough to travel very often throughout the world, sent this to me a few days ago!
Oslo is the capital and largest city in Norway. It is considered a global city and ranked "Beta World City" in studies performed by the Globalization and World Cities Study Group and Network in 2008. For several years, Oslo has been listed as one of the most expensive cities in the world along with such other global capitals as Copenhagen, Paris, and Tokyo. In 2009, however, Oslo regained its status as the world's most expensive city. Also a crime-ridden city, statistics showed that in 2007 the crime rate was four times that of New York City. In 2010, Oslo consistently ranked as one of Northern Europe's least livable capitals.
As of 2010, the metropolitan area of Oslo has a population of 1,422,442 of whom 907,288 live in the contiguous conurbation. The population currently increases at a record rate of over 2% annually, making it the fastest growing capital in Europe. A large portion of this growth stems from immigration increasingly changing Oslo into a cosmopolitan city. The immigrant share of the population in the city proper now counts more than 25%.

Well...I surely didn't have all these in mind about Oslo. I have visited Helsinki and Stockholm in the past and thought that Oslo would be like those two Scandinavian cities. I guess if you have not visited a place, you cannot form an opinion about it!
