We brought the kids (four teenagers!) to DC for a family vacation, and tried to pack as much into four days as we possibly could. Lily's place was a fantastic place to stay. Close to busses and not too far from the metro (it's about a mile away, but easy to just drive to the station and park there), we were able to get into the city every day and see as much as possible. To be fair, we weren't in the apartment much beyond sleeping, but then again, that was exactly what we needed. Thanks, Lily!
