I enjoyed staying at Alex's place in MGM signature. It was my first time staying at MGM signature and the check in was smooth, the room was quite large, and I was able to use all of the MGM facilities including the MGM signature pools and MGM lazy river.
The place was about ~10/15min walk from the strip (there was an indoor walkway connecting MGM signature to MGM). From MGM, walking through the casino, you could enter the strip.
The living room had a sofa that expanded out that was able to sleep an additional 2 guests + the main bedroom. It was convenient that the place had two bathrooms. My only suggestion would be to provide more towels upon initial check in as getting new towels required a fee (and there was no place to wash them) and for the kitchen to be a little bit better stocked (for example there were no basics like salt/pepper/oil).
