This is as close to a perfect location as I've found in Adams Morgan. The apartment is in a reasonably quiet location that is smack in the middle between the 18th St and Woodley Park areas, so loads of possibilities for short walks to dine or evening entertainment.
The apartment has a nice vintage air to it - I liked the brick interiors and smooth-worn hardwood floors. Even the slightly creaky steps up to the unit were charming, and provided a live-in feel unlike some of the other, more "modern" places I've stayed.
The hosts were very responsive to questions and other communications... I'd certainly consider staying there again.
