I stayed at Hao's during the weekend of 4-6 Nov'16 with a friend of mine.
The place was so close to the metro station and so great located that it helped us a lot with getting around. I had a very good communication with our host before the arrival.
There was also a nice surprise waiting for us upon getting to the condo: bananas and a bottle of wine - thanks again Hao! :)
the room was very clean, the bed very comfortable and after such long flight that was the perfect setting for a good night sleep.

i would totally recommend this place for future stays in DC.
