I stayed in Trinity Towers at Polk/O'Farrell between 1991 and 1995. The building has 2 towers about 12 stories high each. On the 4th floor there is a city viewing deck with pool, jacuzzi, sauna, and a health club all with views of the city. There is a drive in garage with elevators right to your apt. My apt had a great floor plan on the 9th floor with large modern bay windows and city views - it was the ultimate bachelor pad. The management was very professional and responsive, and it is one of the best apts I've ever had.
