The condo we stayed in was beautiful, clean, and was great. Alex was wonderful and kept me up-to-date on the things I needed to know.
A couple of things to be aware of while staying at The Signature are the following: we were in tower 3 and it was a pain being in that tower. The valet parking is only there during certain times, so we had to park at tower 2 and hike back to tower 3, as well as hike back to tower 2 to get our car. The pool in tower 3 is only open Saturday and Sunday, so we had to go to the other towers pools or take the long journey to MGM. Be aware the pools all close at 7pm, except the MGM lazy river that closes at 5pm; also the lazy river you have to buy ridiculously expensive tubes ($25 for the small, $30 for big AND NO RENTING). Those minor things were annoying while staying at the Signature tower 3, but I would book again and use Alex as a host as he and everything else was great. The things I listed above are just things that should have been included in the information about the Signature towers.
