Staying at Ha and Justin's was a great experience. Their place is really convenient from RR National airport (the Yellow Line on the Metro is just a few blocks away), Ha and Justin were easy to communicate with and really welcoming, and Justin greeted me when I arrived and pointed out where things are in the neighborhood and beyond. The apartment is huge, clean and comfortable. I'd highly recommend Chez ChEllers to anyone visiting D.C. who enjoys staying with good people, nice, historic neighborhoods, close proximity to mass transit, walkable areas (close to wonderful, hilly parks) and with a flair that goes far beyond a typical hotel room. Plus, Guinness their border collie is a cutie.
