We enjoyed staying at Katherine's place - its cute and comfortable. The bed is comfortable and it honestly had everything that we needed for our stay. Very clean, comfortable and welcoming.
There is plenty of street parking - on weekdays its 2 hour parking in front of the house but you only have to travel 1 street up to get lots of open on street parking.
The neighborhood is in a great location. Its quiet but only a block or two away from a main road and about 20 minutes from the white house as a point of reference. For 2 people a $7 Uber ride.
They do provide transit passes for your time there - we didn't use them because our trip was so short but its a nice convenience to have.
I was greeted by Katherine and her husband Bruno when we arrived - they showed us the apartment and gave us our space - very helpful!
All in all we enjoyed it - its so conveniently located- we were technically there for business (had an 11 am Monday appointment at the Argentine consulate) but it was nice to be able to come up a day early and enjoy D.C.
