This must be the least expensive one bedbroom in Washington. It’s in Anacostia. Anacostia is south of the Mall across the Anacostia River.
If you are used to poorer urban neighborhoods you won’t blink. If you are from a gated community in the suburbs Anacostia might be a stretch for you. The place is a few blocks from an incipient art’s district. There are a few artisanal food places. But it’s mostly 7-11 and fried fish. I went to a SUBWAY for breakfast. I used the B2 bus (less than ten minutes) to Anacostia Metro. The Green Line is about ten minutes to the Archives station on the north side of the Mall. It is a basement apartment with full kitchen and washer drier. Some footsteps upstairs but not late at night. I saw a Circulator Bus offering free rides to Union Station (AMTRAK). Using mass transit I got to the airbnb on a Sunday in a little over an hour from Reagan National. This is a great deal for the right traveler. Everything clean. Great shower, strong and hot. I’d come back my next time in DC.
