Modern flat, very clean and a delight to stay in. The communication about the property and check in process was problem free. Located walking distance to the US Capitol, and the Mall, not only that, very close to groceries with Whole Foods just a little bit further.
We stayed over the weekend so parking wasn't an issue, but could be more difficult during the weekday. We went to the DC Metro Police for a parking pass as suggested, but they advised us that the owners needed to obtain the pass or accompany us for one.
Over all, a pleasant and enjoyable stay, and will place that I would return to.
