The location is great for exploring Shaw, and checking in and out is so easy because of the coded door system. I would note that there is very little privacy (noise-wise) because you are right on top of the owners and there's a large window on one wall which looks down into their house.
I would recommend for a weekend in DC. However would not recommend for a longer stay due to the lack of kitchen and laundry, as well as other related essentials (like an iron, microwave). The addition of those items would help a lot!
