I stayed at Adrienne's place with my family and in-laws. Adrienne's place is as beautiful as shown online. It is sparkling clean and equipped with everything you need and more. As described, there are no markets, stores, or restaurants within walking distance, but it is within reasonable driving distance to the closest ones and to the downtown area.
A note about the area: The cab driver who drove us from the airport when we arrived in DC warned us about the area saying it is unsafe and even tried to convince us to get another place, so my in-laws who were experiencing Airbnb for the first time were very worried. However, one night of stay and seeing the immediate neighborhood the following morning convinced them the driver was wrong. For full disclosure, my parents-in-law actually had a reservation at a hotel in Downtown DC where they stayed for a couple of nights. They stayed at Adrienne's place on our first night in DC and joined us again on the eve of our departure. I could tell from what they were saying about the place that they felt more relaxed and comfortable at Adrienne's place than at the hotel. They enjoyed their stay and kept on talking about how beautiful the house was.
Adrienne is a great host -- very thoughtful and very prompt in responding to my messages. When we arrived at the place (around midnight), we were welcomed with fruits, a box of chocolate, and a bottle of wine that she left on the kitchen counter for us to enjoy. Coming from a long delayed flight and having not eaten anything for dinner, those treats were a lifesaver!
