I worked at US Economic Research Service as an intern (Less than a year)
ERS has a very collegial research environment, with excellent opportunity to conduct independent research and publish. The hours are flexible, and there are plentiful support staff to help with administrative issues.
The office location is not great, though there are some food trucks and delis nearby, it does not compare to the former location in downtown. Many PhD researchers are in cubicles or window-less offices, which is hardly ideal.
