Ayni's apartment was perfect for our stay in DC. The apartment was very clean and equipped with everything you need. It was also in walking distance (30 minutes) to the Washington Capitol and all the other monuments. The H street, a very lively street with a lot of bars and restaurants, are only 5 minutes away. The area the apartment is located in seems to be some kind of a developing area. As a tourist who's not from the US it's a little bit hard to tell if my gut feeling is/was right or wrong on this.
But all in all it was a great experience and Ayni has been a perfect host and very communicative.
