We stayed the month of September at Stephan's airbnb. Everything was excellent! The location is prime, close to lots of great restaurants and shops. The airbnb itself is perfect for longer stars- lots of counter space, closets, great kitchen, laundry/dryer in unit, dishwasher. The hosts are super communicative and live above and make clear that they're there if anything is needed, but everything went off without a hitch, so while super nice and communicative, they gave us space which is great for all us millenial hermits.
All around, it was a 5 star airbnb experience! :)
Unrelated to the airbnb, but for those with a car (we didn't have one so not a problem at all), would say generally parking in DC seems challenging as most neighborhoods seem to require parking permits.
