In a metropolis with a long history of activism and accountability (just consider its ban on plastic bags), The Orchard Garden Hotel stands out. Located three blocks from Union Square, this LEED-certified boutique property even showcases its earth-loving ways in its designer look, with rich natural hues that create a soothing setting in which to appreciate the hotel's eco-efforts: nontoxic paint and carpeting, chemical-free cleaners and organic bath products are just the beginning. But the hotel doesn't stand on its conservation laurels alone. It also offers a stylish City by the Bay stay, featuring plush guest rooms and one of the top organic restaurants in San Francisco.
