If you're not venturing out of DC, you can take the metro to just about everything you'd want to do. You would want to avoid navigating through the District anyway.

Most of the time I'm up there, we're staying with friends & relatives so I'd have to check on accommodations recommendations...! The various museums, monuments, zoo, Arlington National Cemetery, Pentagon, etc., will take you all week to enjoy. Mixed in with a herf or two, you've got yourself an eventful vacation!
