This is a very good place to stay in Washington. Very clean place with a good social space (kitchen, living room) with all the appliances to cook your meals. In addition, the hostel offers a good breakfast included in your stay.
This place is around 25 minutes walk to the capitol, and 10 minutes by bus.
The neighborhood feels nice and safe to arrive late at night.
I only have a suggestion, It is necessary to better organize and tidy up the entrance of the hostel. The shelves for the shoes are quite dirty and messy, it has a not pleasant smell when you get into the hostel.
