Helen's house is in an excellent location, a neighborhood with several nearby cafes and shops, a peaceful ambience, and a pleasant park across the street with a playground and tennis courts. It's a quick drive or bus ride to centers of Seattle nightlife, and less than 15 minutes drive to downtown or the ferries.
Helen greeted us when she arrived, and was a good hostess, friendly and informative. She provided material that gave us great walking tours.
Our only quibbles are that the room is kind of small, and it can overheat if you don't set the thermostat low. But it's a comfy and well kept space, and we still recommend it.
