We stayed a week over Thanksgiving, here is the summary of pros/cons:
PROS: central location to walk to museums/restaurants in downtown DC, clean and well decorated furnishings, fast communications from Douglas, easy checkin.
CONS: while it is a 2br, it is more like a converted 1 br with a small br carved out of the common area so very tights spaces. as others have said and the description states, there is zero hangout area, not even a comfy chair or small couch. windows are facing the street and we had lots of noise on a few of the nights, waking us up at 2 to 3am. no washer/dryer (as stated in description). pricy, given all the above.
SUMMARY: Good spot to stay for a business traveler, as you are centrally located and likely to spend little time hanging out in the apt. but if you are looking for a longer stay or traveling a a family, may be better suited to find a 2br w a larger footprint within a metro or two stop away for the same price
