Ha and Justin were very flexible with our schedule since we were driving from 8 hours away. Their place is very conveniently located to the metro and bus stops. They were very helpful in letting us know how and where to get metro cards, the best places to eat around DC and around their area. Justin also brought in some fresh cut flowers for our stay which was extra hospitable. Their place is very close to many restaurants and stores. It was a little chilly at night in DC but there was also a stand alone heater which worked wonderfully. They do live right above you so you can hear them walking around but if you are a deep sleeper like my friend then it won't bother you. Overall it was a great stay and they were very conveniently located to downtown (via metro or bus) and the zoo (about 10-15 minutes of a walk).
