Clean room, cool vibe but not great for work; my room (concrete walls) was chilly and when I turned up the heat, there was no discernible change in temperature for many hours (and after an hour I cranked it but still no heat!). Combined with the very thin blanket, I had difficulties sleeping in the chilly room. Also, the "library" on the 2nd only has 3 walls and opens to the first floor on one side and so the noise and piped in music from the reception area make it too noisy for work that requires concentration. [And no desk in the room, so I had to work, uncomfortably from my bed. However, the staff were great, the shower was nice, and the bed was comfortable (except that it did not have proper bedding for a winter in DC).
