Nayong and Fred's place felt very homelike--though all the kitchen and bathroom fixtures are quite new and shiny--the wooden stairs and floor and some of the furniture gave the place a more antique and charming feeling.
The neighborhood is residential, but you can see the Capitol from around the corner. The location is great; there are multiple nearby bus stops; two metro stops within a half-mile each; and on foot Union Station is less than 20 minutes and the Mall less than 10.
Nayong and Fred were quite responsive, though seemed a tad slower to reply once I was actually at the place. I would certainly book this listing again and would recommend it to anyone traveling there.
