I can't say enough good things about this place. It checked every box for me. The place is located on a cute, quiet street, a few blocks walk to the metro, and many great DC sites including the Lincoln Memorial, Kennedy Center, the White House, Georgetown, and access the the Rock Creek Park path.
Elliott was very responsive to every question I had and checked in a few times to make sure we were doing ok.
The place was clean and had everything we needed to make our visit to DC comfortable, easy, and enjoyable. I highly recommend staying here.
