Despite the fact that it takes its inspiration from the Mediterranean, the Adagio pulls it off with a modern feel; undeniably one of the most romantic hotels in San Francisco. The Adagio’s recent renovation has given it a certain look: Sleek furnishings in soothing colour palettes are joined by state-of-the-art amenities, such as complimentary wireless Internet, as well as thoughtful touches, like a guest-use umbrella in each room and Egyptian cotton bedding. Given its proximity to Union Square, some of the rooms even boast downtown city views.
