I have AT&T and couldn't get any cellular service at the property, but that was only a problem because the internet service was absolutely terrible. I was getting 1 to 2 mbps max on the Marriott internet service. The whole point of staying there was so I could take some morning business meetings while traveling, and that turned out not to be possible at this property. I won't stay at this property again.
Other than that, it's a very clean hotel, great area, thoughtfully designed, feels safe.
