While i'm not actually flying into D.C., this seems like it would be the best place to post this question and any help would be greatly appreciated!

I'm moving into my girlfriend's apartment in D.C. this week and am looking for a place to store my car short term (immediately after moving in, for about a week probably, and near George Washington University) and long term (after that, probably around 6 months, and likely in Virginia somewhere accessible by public transportation or a friend driving me).

Does anyone have any advice on either? It's far more likely people will know about weekly overnight parking, but if anyone has any advice for long term i'd be happy to hear it!
