Convineant Location
We stayed over the spring break with our children to explore DC. There is a metro station in the lower level of the hotel which provides a central hub to travel to the sites. It is close to China Town and walking distance to many sites (the mall, white house). 
There was construction across the street but there was not a lot of noise - we stayed in a roon in the front of the hotel directly across from the construction (we are use to usual city noise). 
The rooms are a bit small - which should be expected for a city hotel room. There were two double size beds. The beds were not the most comfortable (size and pillow quality). The rooms were average. There is a pool and fitness center. The fitness center was great - decent equipment and clean. The pool was small - afire quality was not so great - but suited the kids. There is a charge for the use of the fitness center.
The lobby is pretty. There is a starbucks cafe in the lobby as well.
