I moved to Oslo (the city mentioned in the article) last week. I have to say Google Maps hasn't always played nicely, if it were not for me having been here before I would have wasted a lot of time.

I have a much better experience using HERE Maps (by "old" Nokia). The great part about them is that you can download a region (not just buffer map data as you do on Google) so searching in the map, public transport, directions etc. all work when in unknown cities abroad without mobile data.
