This is a great place for a long-term stay. I was in DC for a one-month work assignment, and this fit all my needs. They maintain the place immaculately and provide all of the essentials including the kitchen that make it easy to move in on day one. They were quick and responsive to my queries and went out of their way to make my stay comfortable. I mentioned the room was slightly warm when I checked in, and Ken was back in a few hours with a brand-new, quality power fan that he set up for me. I cannot overstate how incredible Ken and Linda are as hosts: I would recommend them to seasoned travelers and first-timers to Airbnb alike.
About the place itself -- fantastic location in Shaw with proximity to everything. Generous spaces with a fully supplied kitchen that made cooking a breeze. Truly spotlessly maintained common areas, and they take the lead in facilitating an easy time interacting with other guests and knowing what spaces/spices/tupperware are free for common use and where you can put your own things.
