The problem could be unique to my room - so do keep that in mind. But my room had a fair amount of mechanical noise in it 24/7. There is a cheap motor in the in-room fridge that causes a loud tick-tick-tick-tick sound every 1/2 second (I counted). And, because it backs up against a wall, it is echoed throughout the room. Also, you can't reach the plug to unplug the thing. Also, the bathroom vent never shut off, which also echoed along the wall. So, that all added up to a pretty bad experience in terms of sleeping.
To put the above in context, I stay at a fair amount of hotels, and, this is my third Hampton property in less than a week.
The property itself, however, is clean and new and spacious and the people have been super-nice.
Also, property has only one elevator. So, if you're in a hurry (and can't do stairs), just keep that in mind.
