The stay at Ahdi and Rachel's place was marvelous. The welcome was great, they were always attentive without interfering with privacy. the other roommates are great to. I didn't had the opportunity to meet Ahdi but the other roomies talked highly about her.
The location of the place is great if you are visiting, with a lot of places to eat around the corner and the must see things of Washington DC are no more than 15 minutes away by walking/biking.
I am really happy they received me at their home.
