The homeowners evidently live on the top floor and rent out rooms on the bottom 2 floors. You will learn this if you stay on the middle floor because you can hear each footstep up above (including a young child, or possibly baby elephant, running about). Additionally, the grass outside of the home in the backyard and front yard is all marked with signs saying you cannot have your pet use the bathroom there. These signs are to be followed vigilantly -- for even a misplaced footstep of your pet on the grass will result in the owner coming out the front door to say "No, I have a sign", indicating the sign which is, as mentioned, to be followed as law. Additionally -- you cannot park during the day outside the home, so you need to find another spot for your car, which is not simple in D.C. Allegedly, this is permitted at a street about a 7 minute walk away, although you may find, upon going to this street, it also has zoning signs on both sides of the street disallowing your car's presence. A garage on the GW campus nearby charges $20 a day, and has a 72 hour limit. Because of this home's location, there are no nearby parking garages besides this GW one.
Nonetheless, the owner is responsive through the AirBNB messaging system, gets back to you quickly, and does try to help with parking. The place is undeniably close to the German consulate, and is in a pretty, millionaire neighborhood with brick homes and manicured lawns. Even though you rent out a room, you have access to an entire kitchen (although the fridge did not work, and denied its sole purpose in life by being actively warm; freezer was good). Bathroom was stupendously clean.
