Very unimpressive
I just spent two nights at the Sheraton Downtown and came away unimpressed. The location is great, the staff reasonably friendly, the price not bad ($179 a night) but that's about it. My room on the 10th floor was old and needed renovation. The plug sockets in the walls were loose, so every time you unplugged an iron or phone you felt the socket might come away in your hand. The air conditioning system was noisy and oddly designed -- when I turned it off there was more noise than when it was on. The bottom sheets were six inches too short so my feet (I am 6 feet 2-1/2) began getting caught by the end of the bed.
What really bugged me was the staff's total indifference to the chaos around them. My stay coincided with a student music festival and there were teenagers wandering around the corridors pretty much 24 hours a day. A colleague had to call the front desk at 2 am to complain about people playing the ukulele loudly on his floor. I mentioned this to the check out staff and they said "Sorry about that" but didn't seem too bothered. I won't be back.
