Great Location, average service
Spent 3 nights here. Rooms are huge and nicely appointed. Staff is friendly but not especially competent. In general, DC customer service is lacking, so the Quincy was average by those standards. Had to replace my room key 3 times, and one night a stranger with a key almost entered our room at 1:30 a.m. WI-fi was problematic. I would return, though, because of the proximity to both the orange and red metro lines, and it is within walking distance of the Mall.
