Norrköping is a medium sized town around 1.5 hours south west of Stockholm. It was a handy stopover for me traveling between Malmo and Stockholm.
I had been to Sweden a couple of times before visiting in October 2015. The stopover was more for convenience to avoid arriving in Stockholm after midnight, instead arriving in Norrköping late on a Sunday night.
A bizarre hotel arrangement meant walking through an office building (I was given the door codes) into a hotel now unstaffed due to the time, where my room had been left unlocked and the key inside. Whatever works!
In all I had a night and half a day in Norrköping. It had been a toss up between there and Linnköping. I got to see the town centre and a wander through an island-like former industrial area and along the river front. Perfectly pleasant on a quiet Monday morning.
