Planning a six night stay in DC in June, arriving Sunday, leaving Saturday. Have reserved a VBRO just east of the Capitol building. Will have a car that we need to park overnight for the duration of our stay. Have checked BestParking.com and a few other sites, but can't find info on the area. VBRO owner says there's a public lot four blocks away for a daily rate of $13/day. Anyone familiar with a lot like that in the area? Would we be better off leaving the car at Union Station for $19/day? Other options? thanks!
