I've stayed in a couple of Airbnb listing before and Ken and Nicole's listing is definitely at the top. The cabin is very comfortable and clean. As many reviews mentioned, it's not smack in downtown but there's numerous mode of transport or you can also drive which takes less than 10min off peak hours. Also Ken has kindly provided temporary parking permit which is very useful because DC is notorious with parking rules and tickets. In short, I felt at home when I stepped in the cabin and if that's not enough to convince you then I've nothing else to add. Whatever reviews you've read about this listing is accurate.
