Azita is a great host and made my stay really perfect. I was in DC for work and to visit family, and the room gives the real sharing feeling while at the same time you have full privacy with your own bathroom and the quiet bedroom.
The neighbourhood is great, though as others mentioned you might need to walk a but for public transport. Takoma has many great places for coffee and food, I loved it and would come back anytime if I would be in DC.
