This is our go-to hotel anytime we go to DC. There are closer (oftentimes cheaper) HIEs in and around DC but we prefer staying at HIE Woodbridge because we always know what to expect. Very friendly staff, clean rooms, ample breakfast, truly high speed wireless internet connection (they have a modem/router for every floor, unlike the HI in Charlottesville that only has 1 modem for the entire hotel). The hotel is centrally located, very good area for shopping and a great jump-off or starting point for seeing the sights in and around the area.
We've stayed in this hotel on 5 separate occasions only in the last 180 days, and we've never been disappointed.
