The space is really large, like a full-sized one bedroom apartment, and is really cute and really clean. Check-in was super easy with the lockbox, easy to communicate via text with host, no need to speak to anyone.
This is a great space to stay. The only thing I would do differently if I stayed again is have a lot more drinking water--I brought one bottle and then was thirsty all night, since there are no stores or cafes within walking distance of the house and DC water is not the greatest to drink. Otherwise, all good.
