We loved this Airbnb. It was exactly as promised on the site. It was modern, clean and a relaxing place to end busy days. While you cannot take the metro (as it is a mile away) - it is only a 15-20 minute uber ride to the monuments, museums and congress.
Clarence was on top of communications and quick to respond. His house is full of amenities you wouldn't expect such as toiletries (shampoo, body wash, etc) but he also provided a few welcome snacks which my kids loved.
The airbnb was perfectly safe and we never worried about the neighborhood. I am bringing this up because other reviews had referenced this a few times. These town homes are fairly new and simply gorgeous. I would highly recommend a stay here while in the D.C area.
