The devil is in the details
Check in was easy and the front desk was well staffed! As SPG platinum we were upgraded to the club floor. The club lounge was easily the nicest Sheraton club lounge I have visited! Evening hors d'oeuvres were above average and included well stocked charcuterie plate, two cheese platters with a wide variety of cheeses, nuts, and fruit, and then two hot options. This was above par for Sheraton club lounges and I was very impressed with both the offerings and the actual lounge itself. 
The room was excellently decorated and everything seemed to be very new. The same was true about the hotel. Nothing seemed tired, worn out, or outdated as can be the case at some Sheraton properties. It is worth noting that the location is excellent as well!
We will not return however because of the small things. Not one of the things I am about to mention actually amounts to any great inconvenience and in and of themselves are very minor, however the fact that all three of them took place in one room on only a single night stay was indicative to me of a culture of inattention to details at best and a lazy mentality at worst. 
When we arrived at our room we were tired and dirty from three days of back country hiking and were most looking forward to a shower however we found the shower dirty and had a inordinate amount of hair on the shower floor. I tried calling the front desk twice but no answer so I ended up just walking down to the lobby to ask for housekeeping to clean the shower. I needed to use the in room safe but a small chest of drawers had been placed in the closet and did not allow for the sliding door to open on the side where the safe was making the safe inaccessible. I asked for someone to come move the chest of drawers so I could use both sides of the closet and access the safe. When we returned to the room the chest of drawers had been turned sideways in the closet and placed against the safe making the items we had unpacked in the drawers inaccessible now. I ended up just dragging the chest of drawers out into the room myself. When the shower finished being cleaned I went to use it and the whole handle apparatus came off in my hand. There were several pieces that came off and after a minute or two of playing with it I was able to get the pieces back together but could not get it to stay together to get the shower to come on. I finally figured out how to hold it just right and was able to shower. These three things were no doubt visible before having a guest check in to the room and the fact they weren't addressed before hand was disappointing.
