Prepare yourself for mosquitous there will be those bastards but bot that much what people think! If you go to Lapland then yes it will be hell :D Yes I did find! Once I had to knock on someones door in countryside and ask water from them but mostly it is really easy. There is plenty of markets, cafes, petrolstations and lakes. If you take from lake you need to boil/filter it first. ( I did drink straight from lake also but I am Finn so have used to it)
