We had a great time staying here! The area is truly perfect. It is within a 10-minute walk to the subway, which will take you directly to the National Mall area. It is surrounded by great restaurants all within walking distance (Laotian, Ethiopian, Cuban, etc.). You have walking distance access to grocery stores and a small mall as well if you need to pick up any extras. Amanda was a great host, we had a bit of an issue and she responded and dealt with it right away.
The only thing I would point out as a slight negative is the noise level. As this place is in the basement of the owners' house, there is not much stopping noise between the upstairs and the basement. Sometimes you can hear everything upstairs, and I'm sure that goes the other way as well. So it can be noisy at times.
