I visited The Inn at Chateau Grand Traverse a few years ago and enjoyed it so much that I went again: this time with friends. All 6 rooms have been renovated and I am a light sleeper: no problems with sound through walls as some people have mentioned. As a 'resident' you have full use of the house: large living room; dining room; fitness center downstairs; tea/coffee room and all the beautiful deck areas. The kitchen is well stocked with anything and everything you will need for a self service light or an extremely full breakfast: I particularly enjoy the Belgian Waffles!
The housekeeping is outstanding and unobtrusive: all rooms are spic and span and while the bathrooms are a bit small, everything necessary for you is there. Each room has a kitchenette with microwave (including complementary popcorn!), refrigerator, glasses, plates and tableware.
The peace and quiet of the Inn is special: other Inns and B&Bs in the area seem to be rather hectic and busy-perhaps some might enjoy having their B&B attached to the winery: I don't and prefer having a private home tucked away, but close to the Chateau Grand Traverse to be a special benefit. Enjoy your nightly complementary bottle of wine: in your room if weather is inclement or on your own balcony. If travelling with friends as I did: we enjoyed a dinner with wine 'al fresco' on the outdoor common balconies off the tea/coffee room and living room enjoying the sun setting over the vineyards and Grand Traverse Bay. I hope to return annually!
