Accommodations offer GREAT value, the parking was/is an excellent bonus as well as having the full kitchen and deck. Had I known/realized the BBQ was available I would have planned to use it for a meal or two! (not a hard stretch with a supermarket just up the street!)
For us driving, entering and parking in the rear was a bonus (particularly in DC where parking can be even worse than NYC!) however I would not like my Wife or Daughter using such as a regular entrance/exit if travelling solo; not that the neighborhood was particularly "bad" at all it was just not confidence-inspiring. Having the driveway, with our car parked offered us enough comfort to spend much of time in the space with the door open to enjoy the Spring breezes through the screen door. Our biggest regret was not getting more time on the deck because of the rain and our schedule.
As a cyclist I loved having the Anacostia Trail right outside my backdoor!
Overall, I would suggest this space and I would love to return.
...and by the way, as noted others, the bathroom is tiny, but the rest of the space is so spacious that such was not a hard trade-off for us.
