This is an excellent crash pad for the D.C. travelers. The house is located in an up and coming neighborhood within a ten min walk to the Mt Vernon Metro station. We used the rail only one day of our three night stay because we found walking to the major attractions was within a mile. Bring groceries and coffee for your trip along with basket style filters for the coffee maker. There is a fully functioning kitchen and comfortable living room. We used the dining table as our work station and found the wifi plenty fast and reliable.
We needed to adjust the water tank to have a hot shower, so if you stay and there isn't hot water, check that adjustment first. If you don't know how, ask Alex. Drinking water from the tap isn't recommended so bring water. There is a Safeway nearby, but not that close, and the traffic and street parking is not convenient, but expected in the city. The house is close to China Town and in a residential area that is on the verge of a gentrifying trend with a diverse mix of ethnic and economic population, very close to newly built and trendy apartment buildings, and remodeled brownstones, yet still authentic and homey.
I'd recommend staying here and may again on my return. Alex is a fast responder and the house is clean. You may find yourself alone with the house or as I did a few travelers from various cities will join you, making it feel similar to a hostel, as no resident lives in the house.
