Johan Nyström is a top candidate for the best coffee in Stockholm. Close to the subway stop and lovely park Mariatorget. They have a sign in the window saying Swedens best cafe (Sveriges bästa cafe). Maybe it’s true. Only way to know is to go there and try it!
On their webpage they say the following: Johan & Nyström is a group of coffee-loving friends with the vision of a better coffee world. Their mission is to promote and roast tastier and more sustainable coffee. Big words but hopefully they follow it up with their passion!
