That depends on personal preferences, I find it very cold (and therefore avoid visiting the Nordic countries between October and February) and I think everyone needs to experience it for themselves before they can know how they will feel.
Better to be prepared for it to be very cold, and leave some layers in the hotel if you find it isn't so bad.
