This apartment was great for my family while we stayed in DC for a few weeks. We were there with our two-year old and brought the grandparents to help with babysitting. It was big enough for all of us with the two bedrooms and the pullout couch.
We cooked most of our meals there and found the kitchen well-stocked with all the essential knives/pans/etc that we needed. Grocery stores were just a few minutes away walking. It was a great location overall and very close to a number of playgrounds (great for families!).
We also found Greg very responsive before the trip and during our stay. I would definitely recommend the apartment.
