Stadshuset is one of Swedens most famous buildings, designed in 1907 by architect Ragnar Östberg, who was very inspired by italian renaissance architecture at the time. Next to it is the newly finished Stockholm Water Front building.
This is my favourite café/workspace place. The staff is super friendly and competent. The space has a nice interior and you can order a coffeepot and stick around for a while. In the warm months you can enjoy sunbeds outside
