The capital city of the United States of America has just as many government
buildings as you might imagine. We did an extensive tour of the usual
attractions, including Pentagon, the White House (from outside only),
Lincoln Memorial, Washington Monument, US Capitol, Library of Congress,
Vietnam and Korean war veteran memorials, National Air and Space Museum
and Arlington National Cemetery. The nightlife seemed to be good in proper
neighborhoods and the public transportation worked fine
(there is a subway station at the Ronald Reagan airport). And of course
you must not miss the Suomikauppa nearby in Maryland where you can buy
all sort of things Finnish.
There is a lot to see in DC.
