I agree with the other positive reviews. It's a beautiful, recently remodeled unit. Impeccably clean. Nice furnishings. Comfortable bed.
The A/C worked great, keeping the place comfy even when the outside temperature was mid-90s. The WiFi also worked great: performance was fine for streaming throughout the unit.
I was initially dubious of the "smart lock" and hesitated before downloading the app. But I was glad that I went for it: the app lets you lock and unlock the door from your phone. It worked great.
We thoroughly enjoyed our stay! This will definitely be our first choice on future trips to DC.
