The Donatello
A Tuscan-theme Wyndham owners' club and boutique hotel may hardly be a traditional San Francisco arrangement, but it's the setup for one of the prime Union Square places to stay for luxury without grande-dame prices or pomp and circumstance. Nonresident hotel guests enjoy all the perks of residents, including access to the lounge with its stunning views and to the excellent fitness center with plenty of workout equipment and saunas.
