Seems to be, Bob- they have a pretty large lot, but allow contract parking for commuters... timing may be sort of key...evenings should present NO prollem. No meters near there, sort of quiet residential, mostly apartment buildings.. and there's a Club/Restaurant called the Quarterdeck 1/2 block away. Never been in, m'self.
May just recon and sample the wares soon.
Hotel has nice meeting facilities.. The Board Room, moderately-sized conference table, cozy room, then the large Conference Room, generic..and sorta cavernous Potomac Lounge, cozier, sorta like a Gentlemens' Club.. cherrio, pip-pip! Harummmph!

Prolly a nice view from the uipper floors. Conference facilities on the third floor. All just minutes from the Rosslyn Metro, Arlington Cemetery, etc.

C'mon down!
