We chose this AirBnb for a 5-day visit to meet my brother's new baby because it's in walking distance of their Petworth home... but our stay truly exceeded every expectation. Pavel's AirBnb is beautifully renovated, perfectly located, he is exceptionally responsive to any request, and he has just a few clearly-communicated asks of his guests -- mostly no smoking, no parties, and keeping the property clean. We raved about our stay so much that my brother's OTHER friends asked us for the address of our Airbnb!
A couple of specific points. The kitchen in this AirBnb is full-sized and wonderful for us because my parents like to cook a full breakfast for themselves at 6am. There is a parking spot at the property that we didn't use but it might be extra valuable if you drive. Also Fort Totten Metro Station is in walking distance, I went there to catch a shuttle to visit a friend in Maryland.
Will definitely stay here again next time we visit our grandchild/niece if we can get a reservation, and have recommended it to the other grandparents :)
