Not bad for a night's stay and a ball game!
I booked this hotel on whim..Noticed a couple days before my trip that I forgot to book a hotel for the night we got to the DC..Got a great rate and bought Nat tickets for $3. Nationals Park is a mere 3 blocks away!
Check in was a breeze, rooms were comfy, yes it was loud because of all the sirens, but nothing some ear plugs couldnt cover up. We had a great view of the Capitol Building from our room.
We went to the McDonalds across the street for breakfast (also was told that there was a subway near by), didnt see any "transients" or shadey individuals, just people getting some breakfast before work. 
10 minute walk to the Capitol Building, a 5 minute walk to the Subway. Yeah, not the best neighborhood, but not worse than some I have seen living in LA and visiting NYC. I felt safe walking back from the baseball game, however, I think the walk to the Capitol Building would be a little iffy at night.
Would I stay here again? Sure!!!
