This Airbnb is top notch.
I would recommend to anyone looking to stay in DC. It is steps away from the Capitol Building just as described and is clean and well looked after. The hosts were FANTASTIC, they let us check in a bit early and at the end of our stay they let us leave the bags until we needed them for our flight home. SO HELPFUL. They even sent us local restaurant recommendations before our arrival that had their favourite dishes from those restaurants!
STAY HERE!!
