Good location for metro access and comfortable!
It's nice to stay in a room with decent soundproofing. No noise through the walls or the ceiling. The location on 14th Street means there is some noise from city traffic, but not as much as a busier street would bring. The location across the street from a metro stop (Orange Line) is great for getting to other parts of the metro area. Not quite in the tourist center and not quite the heart of K Street business district, this neighborhood is still an easy walk to either of those destinations. Also walkable to the White House and, with more energy, to the Mall for museums, etc., but with a metro stop across the street, a quick ride gets you back to your room.
Amenities are more than reasonable for a city hotel. Rooms include microwaves, coffeemakers and minifridges. Beds are comfortably firm with many pillows. In-room heating/air conditioning units are noisy, but that helps mute the street noise. They can be set for automatic shut off or constant fan on and cooled the room nicely during the unexpected a heat wave in April. 
The on-site restaurant charges $15 for a breakfast buffet with limited hours, but there are other, cheaper alternatives for breakfast nearby. Parking is extra, as it is in all city hotels, and is accessible only with a valet service. Internet access is free, however. 
Restaurant, valet, and cleaning staff were very friendly. Front desk staff less so, but not discouragingly unhelpful either. Elevators required your room key and that gave a sense of security. The hotel is smoke free but for the top floor.
