I have stayed at quite a few AirBnBs and Sean's place is, by far, my favorite. He is so quick with communication and super welcoming. His tips for walking routes and local restaurants were so appreciated (and amazing!).
The location cannot be beat. I had a conference at the Marriott and it was so close (if you have a conference at the Marriott or Omni, this is a definite!). However, even if you aren't in the city for the Woodley Park area, still consider this place. I had a meeting down near DuPont Circle and it couldn't have been easier to get to (if you are going anywhere on the Metro Red Line, this location will work easily for you!). Further, the neighborhood feels safe and people are super nice (at least everyone was when I was walking!).
It is a very well-lit area!
In addition, you have everything you need in the apartment. The bed is comfortable and the blankets are so cozy. Bonus: the shower pressure is awesome!
Stay here! You will not regret it!
