In Age of Ultron, Tony Stark's office building / home/ Avengers HQ is a high rise building in Manhattan. It is seen with Grand Central Station in the foreground in north-facing views, so it must be a small number of blocks north of Grand Central Station. It is also possible to see the Chrysler building from Stark/Avengers Tower, so it is probably east of the Chrysler building, somewhere in midtown. But where in specific is the Avengers/Stark tower located?
Has anyone seen an actual address description? And I am curious, what other building is actually in the same location in real life?
