This is actually a fake! I used split toning Sepia/Gold for this one. But it looks like Golden hour.
The last time I was in Stockholm around september 2019 I ended up in Scandic Victoria because they had unbelievable inexpensive rooms available. I don't know what has happened to Ericsson or Kista in general but there were something like a dozen customers in the whole hotel during that weekend.
Of course the weather was rainy on both evenings so there was no point to carry my camera to the top floor bar but hey, at least the service was good because there was just one other customer. Under good weather this would be great place to take golden or blue hour photos over the whole city.
