I will be traveling from Helsinki to Saint Petersburg by train. I would like to leave some valuable items such as my iPad behind in Finland during my stay in Russia because I do not need them and I do not want to have to worry about their theft. Is there a safe place I can store such items for a week? I thought I might ask the hotel I am staying at in Helsinki, but I doubt they would keep them so long. I know the train station has lockers, but that seems a little dodgy. Ideas?
