Very Clean and close to the metro! About a two minute walk to the blue, orange, and silver lines leading you right into the city. Both the bed and sofa bed were very comfortable and there is filtered water for drinking ready in the fridge (brita).
This is a residential area, it was about a 20 minute walk (or only 2 stops on the metro) to places to eat. If you are comfortable with walking or plan on spending most of your day at the National Mall, this won't be an issue for you! Definitely a mini place of respite away from the busy-ness of DC.
