We thoroughly enjoyed staying at Jessica’s place. Very clean and comfortable, yet it felt like a home. It’s a lovely, quiet residential area, but close enough to easily walk to DuPont Circle (10-15 minutes) which has lots of good eating and subway access. Comfortable beds, great kitchen, comprehensive AV system, interesting books and even a few games. There’s a little corner store very close by, as well as a great little bottle shop.
It didn’t cause us any issues, but you’ll need to be able to use stairs to get around the house.
Everyone in our group thought it was an excellent base to see Washington.
