I am planning on taking a RS tour this summer, but will have been traveling around Europe for several weeks before and am worried about gift and souvenir accumulation. I'd like to at least have the option of storing something in Helsinki for eight or nine days. I see that the railway station has luggage storage, but can't tell if there's a day limit. I'll be flying into Helsinki, but leaving by ferry, so I'd like to avoid airport storage if possible. Any information or alternatives would be appreciated!
