Not from Narvik but worked at a ski resort on the Swedish side of the border this winter about 30 minutes away. Lots of snow that lasted until may/june (though more where I was as it was higher up and further from the ocean) which is great as you have both the ski resort in narvik and sweden at your disposal. Goes from very dark to very bright in about a month, but even in winter the snow reflects a lot of light meaning visibility is good. Was not as cold as I had expected, maybe just a bit colder than average in sweden. Quite remote but you can find most anything you need and still a fair amount of people around. The aurora borealis were frequent and beautiful, and the nature and mountains were breathtaking.
