I have been looking for an affordable lodging option for our stay in Washington D.C. (I know affordable is subjective, lol.) Is the Americana hotel convenient to the metro and the national mall? We will be spending most of our stay at the museums. Is there a variety of dining choices nearby as well? I have spent a lot of time researching hotels, but I is quite difficult for a city that I have no real knowledge of. Any other sugestions would be appreciated.
