Of the many admirable things Diana's unit has to offer, my favorite was the bird watching! They keep a wild bird feeder stocked in their lovely back yard, and flocks of Seattle-area birds enjoy visiting it. Then, much to our delight, in the afternoon the chickens were let out. Is there anything more fun than watching a group of hens diligently hunting in the grass and winter garden? Totally charming--as was our hostess, who I wish we had had longer to visit with. (Our trip was work-related and we had too many appointments!)
The unit itself is connected to the main house, with several doors that presumably open when guests are not in residence. The entry used by guests is in the back yard, past the large kitchen windows of the main house, and very easy to find. The apartment's kitchen looks to the back yard and is very functional, with full-sized stove, mini fridge and a small table with two chairs. The bedroom sits interior of it and is compact, outfitted with very nice linens and an armchair. We did not use the TV, but admired its placement.

The forced air heat source (important in this case as it was well below freezing during our visit) was possible to augment with a space heater as necessary.
This place is a great value, and I'd say very suited to guests who like to see their hosts, feel part of the family and connected. A really lovely setting! Many thanks for offering it and welcoming strangers into that beautiful garden. A work of art.
