Sheraton Fan, But Not This One!
I'm a big fan of SPG hotels, but this Sheraton is operating using its own rules.
I checked in for one night as part of a large conference. My first impression of the hotel was the doorman who, while I was paying the taxi, tried to whisk my small carryon bag away to a nearby bellman without asking. For a few seconds I thought someone had stolen my bag! I had to demand my bag back from both the doorman and the bellman, who insisted they would see that it got to my room. We're talking about by little 15lb overnight bag! The debate took me about 2 minutes and the goal was only to get them to hand me my bag back!
Check in was fairly quick, and the front desk associate was nice enough, but when I confirmed I was on a club floor I was told that "This property doesn't do that." It took me about 30 seconds of questions to establish what he meant; that they didn't upgrade gold or platinum members. I find that hard to believe, perhaps they didn't have an upgrade available, but I would have preferred that he be honest. The main point is that I've now had 3 "mini" confrontations with hotel staff within the first 10 minutes. It just puts a dark cloud over the experience. 
When I got to my room I found it to be the exact opposite of what my profile requests. Instead of a high floor, quiet room, away from the elevator, I was assigned a low room next to the elevator that vibrated from music (didn't know the source). It was one night, so I let it go.
The lobby bar was staffed with only 2 bartenders and no visible barracks or support, and it was a huge conference- there were easily 200 people at the bar. My colleague and I each had 2 beers in 3 hours, and it wasn't because we weren't thirsty, we just couldn't get service from the overtaxed bar staff (who were nice, but were about to drop from exhaustion). Room service breakfast was fine, and they remembered the custom items I requested. The server was very nice and apologized for the fact that a paper had not been dropped; he brought one back to me.
I has requested a folio via email so I didn't check out, but had to call a few days later since it never arrived.
All in all, I was really unimpressed. The staff seemed to be "nice enough", but didn't go out of their way to make me feel welcome or comfortable. In retrospect, I don't think they cared if I ever came back, they're so busy it just didn't matter; I was lost in the crowd.
