The Mansion on O Street is one of those hidden DC gems that's been on my "to see" list for a long time. I finally went yesterday for the holiday open house. It is one of the craziest places I've ever been to - if the Smithsonian is the nation's attic, then the Mansion on O Street is most affectionately the nation's basement. (I also walked by the Brewmaster's castle but it is closed on weekends.)
Completely random stuff, like Britney Spears' guitar tucked away in an alcove.
Of course you want a life-sized stuffed bear in your woodland-themed bedroom.
And an Art Deco angel in your personal elevator.
Just don't open this particular secret door.
One of the many, many, overstuffed rooms.
Walking back to Dupont Circle I came across this lovely mural.
