Good location and street parking is very necessary in DC if you are travelling in a car because of restrictions.
Only things to note from our stay on this was the bed covers/duve's were stained and it was kind of disgusting to sleep in them, but didnt have an alternative. And the toilet didn't work when we arrived. We were travelling as a family so me and my dad tried our best to fix it and eventually got it working. The cistern continued to play up and we ended up trying to fix it 5 more times throughout the trip.
Aware this was one of the cheaper AirBnb's, but i would have expected the basics to be good.
