If your going to DC, Marshall & Eva's is great place to stay: The location was great - far enough away from the mainstream to be quite, yet close enough to zip downtown in 15 min. Nice dining around the corner with great food. We had no problems walking with our daughter in the neighborhood after dark. The apartment was stocked with food in the fridge and sundries in the bathroom. The Jazz theme gave a nice personal touch/ flavor to the visit, which a cardboard motel room could never match.
This was my first stay at a airbnb. Wasn't sure if we needed towels, we didn't. If we were hungry when we arrived, there was food available. When it rained there were umbrellas - seriously they had umbrellas. My wife loved the stone shower floor and I liked that the hot water didn't run out, even though I was 3rd in the shower line. We were surprised by the personalized card and treats on our arrival. I'm not sure how they tasted, but my wife and daughter assured me the chocolate was great.
