Louse (and Brian) are warm, inviting hosts. Staying here feels a bit like staying at an extended family's place, a home of an auntie of sorts.
The building itself is a large historical home with a few floors, and many of the rooms are rented out to longer stay residents. Expect to meet other residents during your stay (Louise will also warmly introduce you to others!)
The room itself is in the finished basement, which also contains the laundry facilities, another small kitchen & bedrooms, a small sitting area with a TV, and the HVAC unit next to your private bathroom. When the HVAC is on, it gets quite loud -- closing your bedroom door will filter through a good amount of the sound, but you can't avoid it walking down the short hallway to the bathroom. The room looks exactly like the photos, with a desk, bed, built in closet, and plenty of outlets. Given that this is in a historical home, expect the quirkiness of an older house's foundations -- some uneven floors, tighter closet doors...etc. It also has minimal daylight, which was fine for me, since I was out most of the daytime hours for meetings & conferences. The bed was fine -- not particularly uncomfortable or comfortable.
The private bathroom is not connected to the room, but a short hallway next to the bedroom. It's quite spacious, with two sinks, a huge shower stall (imagine the kind set up for rainforest showers) and a sauna, but expect regular shower functions only. Everything was clean, although personally I would have preferred a lot less scented cleaning agents used in the basement, especially since it's harder to get fresh air in the cooler months.
Overall, if you're looking for a family feel with a good amount of your own space & privacy during your stay in DC, for a relatively affordable price, consider one of Louise's rooms. She will take great care of you and make you feel at home. (Thank you Louise for the unexpected brownies and cake you baked for us going to the conference!)
