We greatly enjoyed our stay in Ballard--Al and Jo were very accommodating and helpful hosts. The house was well-stocked and we cooked both dinner and breakfast there. We made great use of the hot-tub as well, just an excellent spot to hang out with great views.
The house is a bit outside of the downtown Seattle area, but we enjoyed our time in Ballard more than downtown proper. Ballard itself has plenty of places to eat, great paths for running/biking/walking, lovely parks. And it's easy to drive or Uber to downtown Seattle.
