Info For Helsinki

[herefishyfishy]

Today is my last day working in Ireland for a while as I'm off to Helsinki for 5months this coming Monday, will be back every so often to do a spot of fishing with my dad and if I have time see the missus.
Has anyone every fished from Helsinki before either shore or charter before. Any recommendations for where to go tactics etc.
Any info would be great as I will need some fishing fixes while I'm away.
Cheers in advance of any help.
Aidan.
