Fanatastic place in a fantastic location, photos don't show are great this place is. 5 minute walk to the subway and a less than 10 minute ride into town. The Union Market around the corner is very cool with all sorts of foods avaialble and a football pitch behind that to knock about with kids.
House was great for a young family with "stuff" for the kids to play with which was really appreciated.
Car space is an added bonus.
FYI - Beware, if you suffer with insect bites, you will get bitten in DC, take Deet!
