I'm not interested in modern architecture so we found a taxi to take us to Seurasaari island, where they have collected many old wooden buildings from around the country, within a natural forest. Seurasaari was interesting, and well-presented, but the buildings do not open until 11am (at which point you can buy tickets at the buildings themselves). ...
Used Hop-on Hop off bus to get around to see major sites , then had a walk round. Went to the Rock Church, around the harbour, Shops, Trams. Was surprised how nice Helsinki was, major bonus wasn't expecting it to be so nice. ...
