We enjoyed our brief vacation in DC, thanks in part to Tran's hospitality. The apartment perfectly suited our needs as a family of 4 (with two tween-age boys). The location is perfect, too. It's close to the Metro, close to the Capital, and an easy walk to many restaurants and the Smithsonian.
The apartment is as described. It's in a historic building that's in very good condition. We wouldn't hesitate to stay there again.
