The Smithsonian Vacation House was a perfect location for seeing the National Mall and sights, in addition to being close to two metro stations. L'Enfant Plaza station additionally has regular bus services to Dulles, so airport access to both airports is within an easy walk. Grocery store and drug store close by so the location was very convenient for my large extended family. The property manager was an excellent host and was always available on cell phone. He was very accommodating and helpful to our large family, half of whom had to leave a couple days early. House could be cleaner, but this is a minor concern. Kitchen was very clean and we used it a lot. I would definitely stay here again.
