Extremely noisy for this class of hotel
The Sheraton Gunter hotel is an older hotel with single-pane windows and hollow doors in a busy downtown area. Even closed the windows allow in noise from traffic (buses start early in the morning) and massive air conditioners on nearby large buildings. The rooms themselves are good sized and well furnished though with older plumbing. The older cooling system is also noisier than typical for a Sheraton/Hilton type hotel.
The staff were helpful, and tried to get me in the quietest room available, but can only do so much with a building so out of date. The location is good but there are many other hotels with better building quality than this one.
