Greg's lovely house is located in a quiet and beautiful neighborhood and is quite convenient to get to national mall and union station as it's a nice 30min walk. There are restaurants and grocery stores within 10min walking distance.
We had a splendid stay in Greg's house which is beautifully decorated and has everything we need: cooking utensils, extra bedding to keep us warm, shampoos and body wash!
And Greg is also very helpful and resourceful.
