This is apparently a favorite for the company booking my business reservations to DC, as they have sent me back to the Virginian Suites in the last 4 months. I don't mind since I have had great experience while lodging in this property and its starting to be a favorite for me too.
I'll make it brief. It's more bang for your buck. You don't get as much room (suites) and service with the rates offered by the Virginian for any other hotel in DC (specially in DC). It's not the most modern hotel but its offers a peaceful and clean stay. (you can always walk down the street for a $400 room at the hyatt).
Finally I will like to mention the great accessibility of staff on solving some minor issue, which were quickly resolved.
