Brunkebergstunneln - also called Tunnelgatan - is a small street between Sveavägen and Malmskillnadsgatan. The particularity of it: it's a tunnel (well, therefor the name, you guessed it!)! It does not really lead to an interesting place but it can be a shortcut to Stureplan for example. And especially if you like to take pictures, you should go there to check. It is a nice spot for some photography in my opinion! But take care, half of the street is reserved for bicycles!
