We spent 5 nights here during our trip to DC. The location was perfect--within walking distance of the Capitol/National Mall, local stores, and restaurants. That said, we showed up during a heat wave, so we did use our car sometimes--I'm happy to say that it was easy to find on-street parking on the same block as the home.
The home itself was perfect for 4 people (ourselves and our two teenagers). Bedrooms were comfortable and spacious, and it was nice to have two sinks/vanities in the jack-and-jill bathroom. Kitchen was well appointed, although it was hard to find some things and we never did find water glasses. The living area was also comfortable for the 4 of us to relax in at the end of a day walking and exploring DC.
