First off, Katherine and Shelby are fantastic hosts. They give you detailed expectations before you arrive, and are great at replying to messages and communications. They take care of all the little things inside, like lending you Metro cards, having a ton of Roku channel access, wine, lots of sundries like toothbrushes in case you forgot anything. It's really well thought out.
The one thing that can be improved is that the place really doesn't sleep 5 well. There's 1 bed for 2, and 2 futons, but 1 of the futons (the one vertically facing the TV) slantedly sags towards the floor due to its prolonged use for sitting. If you sleep on that one, you will wake up with quite a sore back as I did, so that futon probably could use replacing to accommodate groups larger than 3. The other futon was fine.
Keep in mind that this is a basement, and a few things are out of their control but will impact you if you are a light sleeper. For example, you can hear footsteps of the people upstairs clearly.
Street parking was easily accessible within 2 blocks of their place.
Overall, as hosts, Katherine & Shelby are 10/10. If you have a party of 3 or smaller, it is a perfect place to stay.
