I have to recommend the Willow Lodge in Woodinville, Washington. Far enough away from Seattle, that you will feel like you have been somewhere: close-in enough that you can get home within 30 minutes. Here are some of its many charms.
THE LODGE: Although the common spaces (lobby, lounge, library) might lean a little heavy on the log cabin motif, the guest rooms are absolutely zen. Foresty tones of mushroom and moss (the rooms in which I have luxuriated) combined with European bedding and the extra large soaking tub (for two) give the rooms an unmistakable rustic elegance. All of the rooms have balconies and most, if not all, have fireplaces (certainly worth a request). My favorite thing (strange, perhaps) is the lighting. Nothing disrupts a heavenly night sleep like fumbling for the lights at 3:00am. Unless I dreamed it, an almost imperceptibly soft cone of light over the stone sink guided my way to the loo without so much as dilating my sleepy eyes. That is a nice touch.
DINING AT THE LODGE: There are two restaurants on property--The Herbfarm Restaurant and The Barking Frog. Both offer Northwest cuisine. While I have enjoyed dining experiences at both, the Barking Frog is a far more relaxed experience (bistro feel). If you want oto explore a wine list of Northwest wines, this is the place. But even if you do not dine at the Herbfarm Restaurant, don't miss their herb garden which is on property.
THE SPA AT THE LODGE: On one such occasion I treated my husband to a hot stone massage at the spa. It was a huge hit.
BEYOND THE LODGE: Located in Woodinville, the Willows Lodge is in the heart of western Washington's wine country. Read more here http://www.woodinvillewinecountry.com/wwc.php. I'd have to think, a tour of Château St. Michelle and a romantic cheese-and-wine picnic on the grounds of the Château would serve as an excellent mood-setter.
If you are considering a stay between May and September, you might make a reservation for a hot air balloon ride. Contact Over the Rainbow at http://www.letsgoballooning.com/Seattle/seattle.html.
