Mary was a wonderful host and very knowledgeable of the area. She has a very pleasant place close to all of the major landmarks. My girlfriend and I had no trouble accessing all that there was to see around the National Mall on foot, but if you are inclined the bus route and rent-a-bikes are very close to her flat.
She made us fresh bread every morning ... yummy! The bed was comfortable and the home neat and tidy. We would stay here again.
