My friend and I stayed at Ken & Linda's place for 7 weeks while we were interning in DC. We shared the Blue Room, which was a bit of a tight fit for two people long term, but totally doable. The house was impeccably clean and well maintained -- any issues with maintainence were immediately taken care of, sometimes and usually on the day of. Ken and Linda were always kind and flexible, very easy to reach at all times. Overall, would recommend 100%. Was particularly a huge fan of their nicely renovated and fully equipped kitchen.
