Very thoughtful host! Kathy had the house cooled in advance of our arrival and had cold water bottles in the fridge. The house was very clean, well stocked, and exactly as described. The parking in the back (fit two cars) was a huge benefit for this part of DC where street parking can be a challenge. It was a 30 min walk to the National Mall (very flat) and a cheap Uber ride back. Only downside of the location is the proximity to a metro station - the closest one was over a mile away.
Overall a great stay and I highly recommend Kathy's place.
