Sam's place was ideal for my stay.
Very short walk to Trader Joes, Whole Foods and Foggy Bottom Metro (perfect if you interest is monuments and Arlington Cemetery no transfer needed)
The area is 10 - 15 minute walk to George Town and Dupont Circle area. The view is open and bright and although on the street I found it very quiet. Also found some good restaurant's near by.
Building Staff is friendly when you see them but non intrusive.
The Neighborhood is safe and a good mix of residential, hotels and business.
