Great value place--would stay at again if I were in DC. As to some of the reviews that discuss cleanliness, I'll disagree with them on one point: this Airbnb is clean, but it is worn in the bathroom. Some simple changes (replacing the shower curtain) along with a deep clean of the bathroom would go a long way. Not to say this place is bad--it just isn't the crisp, white bathroom many travelers are used to.
If you're in DC and want to stay at a place for half the cost of hotels, this is an excellent option.
