The quality of air in Helsinki is great compared to other capital cities. For example in Hongkong or South Korea the air pollutants have blackened the walls and one can feel them in the air while breathing.
The Central Park in Helsinki is fabulous, a whole forest in the middle of the city. One can walk from the city centre to the Olympic stadium and go swimming or go hiking in the nature.
