The Peace room in the Meditation house is a good place to tuck away near Walliingford and Fremont. I parked on the street and walked everywhere one day (plenty of parking), and the next day hopped in my car and was downtown in about 12 minutes. The view of the city at night from the hills around the house are stellar, too. I had heard of Gasworks Park, but never seen it; that's where my run took me on the first (sunny?!) morning in Seattle for a short visit. Nice family-run spot.
