I trully recommend this option as the best choice to enjoy DC with a family. The appartment is great: comfortable, clean, beautiful, with all you need to enjoy time with the family: microwave, refrigeretor, wash mashine, videogames and so on.
Matt as a host is outstunding: he left us a lot of ammenities, cards for pay the public transportation system, even umbrellas for the rain!! The appartment is located in a pretty neigbour, close by bus to the monuments, museus and restaurants, and very quiet at night. We enjoy the days we spend there and we can't wait to repeat the experience in the future.
