Our stay at MGM Signature Suites was adequate, but not special in any way. It was convenient to have the full kitchen, and it had all necessary plates, cups, pans, etc.
The host was pretty quick to respond but it took a day for the request to be fulfilled.
However, having stayed at this hotel directly through MGM previously I was familiar with the hotel, loved the location, room setup and quality and the front-desk check-in (so I thought). Basically you get what you pay for, front-desk does not treat guests staying through Airbnb the same as “MGM” hotel guests. We got a photocopied black and white map and not the one the person before me got in color on nice paper. The units are owned by individuals, but look like all the other hotel rooms without the same quality standards and standard amenities of the hotel. Housekeeping is not included, which not only means that you will be responsible for maintaining your room (no where to take trash, you have to pay for trash pick-up) you cannot get additional towels, soap, shampoo, etc. without incurring additional fees. The unit could use overall updating, the carpeting has stains, the living room furniture looks used and abused; stains, holes, cracked. The pillows are very flat and feather, if you want something different or more there is a charge. The shower in the master bath was not properly sealed and water poured out onto the bathroom floor with each use, the bathroom sinks leaked and got counter all wet. The microwave didn’t work properly.
In short, we had a satisfactory stay, but certainly not the comfortable, upscale experience that we were looking forward to and would pay the extra money and book directly through MGM in the future.
