So I Googled the map for the Stockholm Courtyard set to open early next year (yay!), and the closest metro stop (Thorildsplan) looks to be a ~500m walk. The satellite view, shows one must walk on a rotary and over train tracks. Would getting to public transit really be less ominous-looking than that?

If so, then it actually doesn't look like it would be a bad option for public transit into the Old Town, or the rest of the city for that matter.
