The house and it's location to downtown is great. The pictures are accurate and it is a great place if staying for business or even a small family. The off street parking is a huge plus as well. Close enough to Yellow/Green Metro to be convenient. Even from a Metro Bus perspective getting west toward National Cathedral/the zoo or east to Union Market was an easy trip.
The only issue we experienced was not something house/host related. Be aware that 9th Street is pretty busy on the weekends (Friday night through Monday morning) and the traffic can be rather loud those nights. If you intend to enjoy the closeness of 14th or U Street, you likely won't even notice.
