Great location. You will be in the center of actions in DC. You will have access to subway, and the national mall is only 15-20 minutes of walking.
The room is clean and beautiful. The window looks right out at the street, so car noises (mostly police sirens) might be a problem if you are a light sleeper.
But it's a very nice place to stay for a short time, a long weekend perhaps.
Carolina is a superb host, and she can give you an extensive list of places to eat and drink.
We had a very pleasant time staying here.
