Staff was great. Rooms were meh. Stayed overnight for a Christmas party- girls night out. First room had no doors to the bath. Second room had a view of a wall (dark) and the furniture was odd. Coffee maker was broken and only one pod. The rooftop is still one of the best in the city. Lobby bar was nice, but I miss the old one in the front which was classic and cozy. It’s a historic building and too bad it got “over modernized). Still it’s nice for DC.
