Barbara is an amazingly welcoming host. I was looking for a place to stay in DC as I was about to start an internship the day after, flying from France. She responded to my booking request within a few hours. After a week staying at hers, I decided to extend my stay for 2 months.
Basically, you will enjoy all the basement of the house, with a spacious room, a clean bathroom/toilets, and a separate kitchen space.
I would strongly recommend this place for a stay in West DC.
