Sonoita is horse-and-dog country. Built by a co-owner of the racehorse Secretariat, the inn was designed to look as if an old barn had been remodeled into a luxurious hotel. There are 16 large guest rooms on two stories surrounding a spacious common area which extends to the roof. Each guest room is named for a local ranch, with photos and plaques describing its history. There's a big stone fireplace with sofas and chairs nearby for lounging; giant chandeliers that look as if they came from a blacksmith's shop; distressed wooden floors; aged brick walls; and a front entrance that looks like the door to a barn. There's a small kitchen adjoining the common area, a fridge, a cooler with yogurt, milk, bread, hard boiled eggs and such, a large hutch with dishes, cereal, teabags, microwaveable popcorn, cellophane-wrapped pastries, toaster, and microwave. There's a coffee machine of the sort you find in convenience stores. The complimentary wine and cheese is only offered on Friday and Saturday (though you could try begging on other days.)
As you can see from other reviews, this isn't for everybody. Because the staff leaves at 5 or 6 pm, you may either revel in the freedom to do whatever you like in these splendid surroundings, or fret because there's nobody to wait on you. If a friendly black lab shows up in the common area in the morning, you may either enjoy tossing a tennis ball for it, or wish you had stayed in a chain hotel that bans pets.
I think the common area is great. If you happen to be the only guests, it's like having to yourself a living room that belongs in a mansion; otherwise, it's like being in a grand old-fashioned lodge where you get to meet and mingle with the other guests in front of the fire in the evening while you listen to the coyotes in the distance howling at the moon.
There are downsides. Some members of the staff are as obliging as can be, but at least one member is abrupt to the point of rudeness. It's never happened to me, but if there were other guests who were disposed to be rowdy, there would be nothing to rein them in after 5pm. There's some deferred maintenance: the towel bar in our bathroom fell repeatedly, the lock on the front door of the entire building required some coaxing to stay engaged, and the knob on the door to our room required so much fiddling to unlock that we were afraid to lock it lest we be unable to get back in after 5pm. The gas log in the fireplace was sufficiently fiddly that the staff member who helpfully lit it for us told us to leave it on all night rather than risk messing it up. Dining in Sonoita has historically been a bit unpredictable: restaurants open and close various nights of the week, and from month to month, and from year to year. The two convenience stores close mid-evening (though gasoline is available all night.) And it's a long way to the next town in any direction.
