Great location in a safe and quiet neighborhood but only a few blocks from Adams Morgan, Woodley Park, the Metro, and DuPont Circle. I was visiting for a conference so I was away from the place most of my stay, but it was exceptionally clean and well appointed and I would not hesitate to stay there again. I was very impressed with the obviously recently remodeled kitchen and bathroom, and the bed was very comfortable. The HVAC units also appeared to work well.
Initially I was a little concerned about the place being a block or so from a main street since I knew I would be returning relatively late at night, but my concerns were not warranted. The neighborhood streets were well lit, there were still plenty of people out, and I didn't feel one bit unsafe walking back to the place after midnight. So if you have reservations about booking because the place is off a main thoroughfare, don't.
