There are many reviews about this place. Hence I will be brief:
Great value; as advertised; truly private; great shower. Having stayed in a few DC area basement Airbnb units, I found this one had better light than other similar units.
Minuses are well documented and clearly shown in the description and prior reviews: Lack on a kitchen-type sink does get to you after a while. And, you just can’t (even for someone like me who is a heavy sleeper and generally doesn’t get bothered with extraneous noises) escape the creaking sounds of people walking on the floor above.
Overall, a lovely place and great value for my week and a half stay!
