As my first AirBnb experience, I have to say that Sylvia's place was absolutely the best. We parked conveniently in the rear of the space and left the car there for the rest of our stay.
In terms of amenities and comfort, everything will be taken care of; no need to worry.
For transportation into the heart of DC, the Metro station is only a 10 minute walk away. If walking isn't your thing, you can Uber in.
P.S.
Do not touch the button in between the windows. :)
