The very immediate area might seem like bordering on sketchy, but the apartment is very nice and secure.
It's only 2 miles from the National Mall and I was comfortable walking to the museum I visited and back, in the daylight of course.
There is free street parking so I was able to leave my car there for free, and I was able to find a spot nearby and late at night with no hassle.
The host was also very accommodating and flexible with short notice and my changing schedule.
