This review is specifically for the MGM Signature Resort, Las Vegas. Suite 14-809. Our stay was from 12/19 - 12/22. Louis & Marie (Marie being the one I was in constant communication with) was excellent from the start. Marie was timely in her responses and made our check-in a smooth one, thanks to detailed instructions about the process. Within hours of our stay, we noticed a few issues: 1) the mattress sagged severely on one side and became an issue at night. 2) there was a leak at the base of one of the bathroom sinks. 3) Not all of the channels on the TV had sound. It was a broadcast issue, not a mechanical or electrical issue with the device. Marie responded to all of our concerns. Practically, the mattress could not be changed during our visit. Management did not resolve the TV issue, but the onsite building engineer fixed the leaky faucet within hours. I mention the date of our stay to determine if problems have been resolved before the next guests pick this particular suite. Nonetheless, I would recommend Louis & Marie and book again at one of their properties. The MGM Signature gives you a quiet base when spending a few days or longer in Vegas.
