Ken is perhaps the best AirBnB host I have had during any of over 25 stays in several cities in the U.S., in Mexico, Spain, and France. The place is not fancy but it is warm and hospitable. The location is great if you are using the Metro to or bus to get around Washington, and taxis come up an down South Capitol St., a block away, all day. There is no grocery store next door, but I usually go one Metro stop to Waterfront and shop at Safeway, just outside the stop, and then return with only two blocks to walk with bags of groceries. If you're interested in seeing a Nationals' game the park is a block away.
At Ken's I have access to a kitchen to prepare my meals, including those I take with me to work during my 2-3 week stays. I have a washer and dryer. The bathroom is clean and fully stocked with anything I may need and may have forgotten to bring.
The best part is Ken himself. He's picked me up and taken me to Reagan Airport (at no cost) when his schedule has permitted it. He is easy to reach and to make arrangements to get to the townhouse even when he's not around. Converssations with him are always interesting, and he leaves me alone when I have to have time with myself. I have stayed at three other places nearby when Ken's place was booked, and Ken's is the best, for value.
