Tom and Adam are great hosts! We stayed two weeks while visiting the National Archives and found the location very convenient to the Metro station, with a short ride to the archives stop. They gave us plenty of privacy but were very friendly and checked in on us when we saw each other in passing to see if we needed anything.
Our favorite nearby dinner place was Ten Tigers Parlor, right up the street from the metro stop.
Tom and Adam have a comfy space. They also provided good coffee and a coffee maker, which made making it to the archives in the morning a lot easier.
