Joe's place is great. It's in Tower 1 so it's the closest walk to MGM Grand. There is a covered and air-conditioned walkway from The Signature to MGM.
What I like about Joe's place is it's close to MGM Grand but not inside the casino/resort hotel that the lobby reaks of cigarette smoke.
The space is also spacious. There is a kitchen but its a bit difficult to cook since the kitchen utensils are a bit limited (no diswashing liquid and some stuff). But you can help yourself with a simple breakfast with a toaster and a coffee maker at Joe's place.
The best feature of Joe's place is the bathroom. It's big and the jacuzzi is just divine! Parking is also easy as they have a valet parking at the Signature.
In terms of the location, it's the other end of the strip... so that is a plus and a minus on its own. We are a family travelling together, so this was ideal for us.
Overall, we had a very good experience at Joe's place.
