I was in SF for a meeting and stayed for 4-nights at the Westin San Francisco and enjoyed my stay.
The rooms were very nice- modern and comfortabel and although my room layout was a bit quirky, I had a wonderful view of the city. The concierge was fantastic and helped get tickets for tours in the city and they were very responsive with good suggestions for places to eat.
The gym was reasonably adequate, and the pool was more for a dip than a swim.
Internet access was good, but my one complaint was that the restaurant in the hotel is not very good, although there are a number of good restaurants nearby, so this is not an issue, unless you are in a hurry in the morning.
Overall- a good hotel, with a nice location; I would stay here again.
