Good location for convention.
Enjoyed a 4 day convention here in an executive suite in the Tower building. This hotel has 2 buildings: the "Plaza" which houses the main lobby and the "Tower" which is across the street and is connected underground and by a second floor enclosed bridge. Our room with 2 queens and separate sofa/lounge area was very large and pleasant, while the bath was quite small but still usable. 
The staff was very nice although we had a slow check-in when they sent us and several other guests to rooms where our keys didn't work. It was the wrong building too. 
The conference areas were well organized and easy to locate. The hotel is located in a great area where you can walk to lots of shops, bars and dining. This was a nice perk since we didn't have a car.
The (convention) food was disappointing (I've had much better convention food at other Sheratons) and it seemed the hotel didn't assign enough staff for the approx. 800 attendees. The waitstaff was accommodating with special requests when we saw them.
