We stayed for a full week in this beautiful home. It’s just lovely; I would happily live there! The beds are extremely comfortable - we kept talking about how nice they were, the kitchen is well-stocked, and everything worked well. I lived in DC ten years and the location is great - close to metro, walkable, near stores etc. We got the visitor parking pass from the hosts easily and could usually find reasonably convenient street parking.
The only drawback would be sound. The floors are quite creaky everywhere, so might be an issue for light sleepers. During the week noise outside was reasonable, but on both weekend nights there was a group of people that hung out in the road right outside the house playing loud music at 3/4 am. Not the fault of the hosts but definitely disruptive. I would still have chosen to stay at the house but it might be good to have white noise machines/ear plugs provided or bring your own supplies if you sleep lightly.
