Noisy!
This is a run of the mill Hyatt that is one of the noisiest hotels I have ever been in. My room was close to the ice machine and it sounded like it was IN my room all day and night. Outside traffic noise is not at all muted and very loud with excess truck noise. The halls are noisy, the door slamming was noisy, the rooms next to me were noisy, the housekeeping carts were noisy. you get the idea. BUT worst all was the noise from the fan going on and off on the air conditioning unit in the room. Constant, loud and very irritating. Even ear plugs could not block it out and I had trouble sleeping all nights that I was there. The rooms were fine but don't stay there unless you have to.
