This is an affordable way to stay close to the Mall in DC. The bed, futons, and cots are all fairly comfortable. There is a very small kitchen area in the main room of the rented area.
Note that you are on the lower floor of an old town house with a family living above you. It is not quiet during times when kids are awake. Additionally, you will need to stay quiet at night out of respect for the family.
The only other thing to be aware of with this house is the location. You are very close to the Capitol and east side of the mall, but it is a very residential area. It is a bit of a walk to get food or entertainment, although a metro stop is nearby.
Overall, our group enjoyed our stay and this location is useful, even if there are some small flaws.
