Sylvia's cozy apartment is in a wonderful neighborhood, walking distance from many sights, galleries, and breakfasts (Kerem's Eritrean, Woodley Park diner, etc).
After walking to breakfast, we walked to the Phillips Collection, and from there to the Kennedy Center. The metro is also quite convenient if you aren't in the mood for walking. Definitely a great location to see the city.
She reached out during our stay to ensure we were comfortable, which was a nice touch.
