Welcome to Helsinki!
If you plan to stay few nights - there is 2nd division (level 4) game on Friday evening just next door of Bolt at 7 pm. Tickets just 10 € and local small brewery beers 8-9 €. So collect your new stadium point, oldest football turf in Finland (1915) that was used also in 1952 Olympics. And cheer up for Kiffen vs Union Plaani.
