I had a good stay. The location was super-convenient for all my weekend activities. It really is just a few minutes walk to Union Station. And just blocks from the National Mall. Windows face away from the street so didn't hear most of that noise (except for one very persistent dumptruck one morning). All the appliances worked and the teapot was a nice extra.
If most of your activity is around the National Mall or at one of the nearby hotels, definitely consider staying here.
