If you want to try something outside the city center this is a really beautiful small gem. They cook delicious seasonal food and have a nice selection of cheese and charcuterie for your wine. Best to book table beforehand. 

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.

A 500-meter long (quarter mile) walking path with a magnificent view of Lake Mälaren, City Hall, and Riddarholmen. Bring your take-away coffee and walk the path at least once every season to notice the different scents and colours of Stockholm.

Super cute and airy café with nice green lemon tea and nice coffee. They only take cash.  Perfect if you are around Slussen. 

In the summer this is a haven in the middle of the city. It is a public garden where I like to go and relax in the grass under a blooming tree. There is also a cafe and a shop here. Before you leave you should buy a bouqee of flowers (you pick yourself in the garden!).
