Average Hotel
I stayed here for a conference recently. Check-in was a little timely. Arriving before check-in time, I was hoping to be able to get into my room, shower and freshen up; however, no rooms were available prior to 4 pm. The lobby and surrounding lounge area was loud. I checked my bags with the bellman and left. The metro stop is about a block away, which was convenient. 
Room service was done well. Watch the charges though because the tip was already calculated into the total. 
The room was comfortable and clean. I think the sound proofing could be improved. 
The hotel is tucked into a neighborhood and only 3 blocks from the National Zoo. 
Would I stay here if I was not attending a conference that was being held there? Probably not.
