Ken was extremely responsive to our messages before arriving and was able to quickly accommodate us once we arrived at the airport. The place was beautiful and in a nice area close to many restaurants and outside of the busy downtown core but within walking range (~15 min) to the sightseeing of the National Mall area. It's also close to transit.
I can't say enough about how pleasant Ken was to deal with and how much care and concern he showed in making our experience the best as it could be while staying there. His attention to details, right down to the individual key sets he gave us was impressive. I would recommend this place to any group of two to four travellers. Having two full baths made it easy to coordinate morning schedules.
