I staid at grace place for a week in dc with 2 of my colleagues. The flat is really clean and spacious. All you need to live like at home are in the flat so don t worry bringing your own staff .
More importantly the location is perfect. Close to restaurant and downtown (20min walking) with a Safeway and a pharmacy at 2min walking
Grace was extremely nice and super reactive
Do not hesitate it s a perfect plan on Airbnb
