I had a great stay. The apartment was exactly as pictured. I didn't meet the hosts in person but they were very responsive and had many nice extras that enhanced my stay: wine and chocolate, brita pitcher, refreshing bath products, luggage rack in the closet, and a space heater. It's a lower level unit but doesn't feel like a dungeon. The space heater came in handy at night when things cooled down a bit.
Also, this place is in a fun neighborhood. It was a pleasant walk over to the main streets of Ballard for brunch and browsing. Good overall rental.
