This accommodation is, in most respects, even better than advertised. The host provides the advertised amenities, and, in addition, a little library, a fan, snacks, and a COVID self-test kit in the room. The host also provided a charging adapter when I needed one. The room is quiet.
There were 3 issues, however, that should be corrected for future guests.
(1) The second entry ceiling lamp in the room turns itself off and on every minute or so when the ceiling lighting is switched on.
(2) The only hot water in the shared upstairs bathroom is that in the bathtub. The basin’s hot water does not flow.
(3) The staircase between first and second floors is out of compliance with DC Building Code Sections 1011.11 and 1014, because the top 10 risers have no handrail. This is a hazard. If a guest tripped or stumbled and started to fall, there would be no handrail to grasp. This could cause serious injury and owner liability. The cost of attaching a handrail to the wall would be minuscule, compared with the risk avoided.
