This was out first airbnb experience in DC. Though it's a basement, stylish and clean as described, we had some trouble locating the back of the house, building are so close to each other there so google maps tell you you've already here while you still have to figure out the entrance and going around the block to try and find that small turn. Also we saw some bugs at least twice, but maybe this is due to the basement location, and probably Sina is doing something about that as well.
Overall is was a good experience and I would recommend this place for a short stay in DC, the location is convenient for many tourist attractions.
