Funny enough, I have lived in Norway 3 times, short periods mostly and once as a mere small child, so I have no memory of that time. But still, I have rather enjoyed my time in Norway, compared to my home country. Especially the nature is amazing. the single best moment in my whole life was in Norway, when I was 14 or so, and I climbed to a mountain, alone, listened to music, watched the magnificent views of the fjords and the sea, ate the food and drank the drinks that I had in my backbag. I really, really miss those times and I regret that I haven't been able to do that even though I have been in Norway many, many times before. Just not in the north. The "mountains" that are in the places where I am are not like in the north and are just full of trees, which is annoying as it limits the view a lot. I like the rock based mountains in the north
It's funny because when I visited Oslo, it was one of the best place I'd ever been! But I guess places are different when you don't live there. It's a very subjective question, though - if you could travel a bit first, then you might find somewhere you like?
I like Norway too. Did you go anywhere else than Oslo? I personally never liked Oslo that much but the north I like way more, especially in terms of nature. Bergen, Tromso, Lofotes and so on. Cool places.
