Wahid's place is in a great neighborhood - Mt. Pleasant - and is close to a lot of great things in DC. There is a great restaurant, Dos Gringos, next door, too. The room I was in had everything necessary - comfortable bed, places to put my clothes, and a window overlooking the street.
Check in instructions were excellent, finding the room was easy, even though I arrived late at night, and I can't think of a thing I would change about the place. If you're looking for clean, basic accommodation at a great price in Washington, this place should be on your list of considerations.
