This space is gorgeous and very conveniently located. Dupont circle has tons of interesting shops and restaurants, and this is literally right next to it all. There's easy public transportation (route 42 gets you close to most places you'll want to go downtown), and Uber or Lyft drivers are plentiful nearby. It's actually only about a mile from the White House if you want to take a stroll that direction.
Check-in is super easy. The bed was very nice, and the furniture all feels very vintage. Parking is an issue if you have a car. There's basically no street parking and the garages are kind of expensive. But as I noted above the public transportation is really good. So ditch the car if you plan to stay here, and wander around on foot!
Nicole was very responsive. You're kinda left to your own devices compared to other places I've stayed, but that means privacy too. I recommend this place to anyone looking to explore DC :)
