The house of Matt is located in a perfect location for a visit in Washington DC. A few blocks (5-10) minutes of walking to the metro station on the red line that will take you to downtonwn or Dupont Circle in a timely way. There is a WholeFood grocery store, a liquor store, a CVS and several restaurants (Indian, Mexican, Peruvian, Italian) around the station.
The neighborhood is very clean and quiet. We did not had childrens with us during the trip but I've remarked that there is a lot of toys and equipements to accomodate young childrens.
My only regret is that our trip was planned in mid-october so we did not had the time to appreciate longer aperos in on the great rooftop patio.
