Another convention home
.This is the 3rd time I have had a conferance at this hotel. Overall the place was clean and user friendly. The standard Starbucks off the lobby, a lobby bar, and a nicer restaurant at the top of the tower. THis hotel is conferance friendly. The business center is in the basement where many of the meeting rooms are. The Fed Ex there charges a HEFTY charge for sending out. However you are pretty much trapped. 
The housekeeping staff were friendly &efficient. The room was comfortable. The dresser drawers are large and deep. I prefer more drawers that are not as big (not small mind you.) It is easier to divide clothing. There is free wifi in the lobby not in the rooms . However the sitting for using a computer is NOT comfortable. Friendly seating for just visiting though. 
The loccation is prime if you are going to the convention center. There are 2 upscale diverse food courts and a hardware store right there. Green space is less than a block away. Good shopping and eating are an easy walk as are the street cars. It is also an easy walk to BART (the subway). 
If you are looking for good concierge advice it depends on which one you talk to. We had both good and not so good experiences with their advice.
