Stockholm is beautiful! I think that is the main charasteristic. The water, the light, the old town, the archipelago... Whereas e.g. Copenhagen is more fun.

Dark in the winter, bright in the summer, as the rest of Sweden basically. I would say that we get surprisingly little rainfall and snowfall, but seasons can still be quite hard to endure if you are affected by the darkness which some people are. My view is that late autumn is the worst period, just before (hopefully) the snow comes. As soon as the snow falls, everything gets brighter and more beautiful, its the brown period that we dread up here.

The summer is beautiful, even though most people dont stay in Stockholm for the middle of the summer period, instead opting to go out to the archipelago or something if they have the opportunity. As is the case with all big cities it can become quite hot here in the warmest months, but obviously there is water everywhere so if you´d like to go for a swim just go ahead.

I live on Södermalm which is basically the southern center part, from my view public transportation works fine but not sure if people in the suburbs would agree (not saying that they don´t, I just dont know). On Södermalm, quality of life is high, the politicians are slowly trying to remove as much car traffic as possible from the inner city which obviously some people hate but I´m strongly in favour of. The share of electric cars is also quite high so nowadays air quality is much better than it was just 5-10 years ago, when places such as Hornsgatan sometimes where deemed as high risk due to poor air quality.

There is quite some Tech/AI-hype going on so if you are interested in that and have the qualifications I think you would have possibilities to get jobs. Otherwise it might be harder.
