Hyatt Regency San Francisco
This hotel looks great from the photos but is a bit of a let down when you actually stay there. The inside is like a giant hollow beehive meets shopping centre. All of the business end of stuff is in the atrium which is the floor of the hive. The lifts are see through and all at one end, as is the reception, concierge, check in and main restaurant and bar. There are several veils of lights that cover the restaurant area giving a spectacular appearance. 
The rooms are variable in size depending on how they have been fitted into the beehive shape.
We had a good view of the embarcadero and my sons' had a good view of the street. Our bathroom was small but their bathroom was tiny. 
The concierge was particularly helpful. The breakfast was good but not marvellous. On our first morning the service was totally overwhelmed by 3 tour groups having breakfast at once. A single line buffet for such a group was destined for failure. Even when quieter over the next two days it was a struggle to get more than one cup of tea/coffee. 
The biggest nuisance was the non stop non musical music with a big base blaring around the atrium from dawn till very late. 
Our first hotel on this trip was the excellent Manchester Grand Hyatt in San Diego and we were looking forward to a similar experience. We didn't get it.
