Mark is a great host! If you have any questions or concerns he is quick to reply. His place is nice and clean. You definitely have access to the MGM Grand casino, pool facilities, etc. We stayed in tower one and it connects to the MGM Grand hotel&casino area. You don't have to walk outside! Tower one is close to Wet Republic pool which was a big perk for us. Check in and check out was easy. The room had 1 bed and 1 sofa pull out bed, perfect for a group of 4 people. Overall, we had a good experience during our stay at Mark's place in tower one. We will definitely book with Mark again.
