I'm an SPG gold member, and frankly, I'm surprised that Sheraton would put their name on this place.
The Bad:
Dirty, dated rooms
Rude desk staff
Rancid food from room service
MIA management staff - there was "no MOD" during my stay
Outer doors other than main entrance have non-functional card readers
The good:
The location is fairly central
Jon the bartender - very kind
Costa Vida is right across the street (you'll want to find a different food option)
In short - avoid this place. The Aloft Tempe is just down the street, and it's a far superior Starwood property. I've stayed there several times, and they will treat you like family, unlike this place. You can do better!
