Mixed bag. It was clearly recently renovated, fairly well-appointed and very clean.
But it is also a cave-like basement with very low ceilings (if you are 6 ft, you will hit your head), and there is a LOT of noise from upstairs. Sounds like wood floors with no rugs, little sound insulation between floors and people running around.
Space is more of a large-ish hotel room equivalent with a kitchenette, not a 1-bed apartment space with a sitting room or common area.
Neighborhood is fine, but probably not ideal if you are in DC as a tourist or on business, because it is not terribly convenient either way.
