Lured by an AAA bargain rate that (surprise, surprise) wasn't available, my wife and I stayed here in early March 2006. As others have reported, at that time there were signs up announcing "rennovations" but these seem to be a more or less permanent part of the decor (they'd been up since the previous winter). While the rooms were clean, if spartan, the halls were dingy and the hotel fairly unpleasant and not much of a bargain. It's located in a vast wasteland of shopping centers (the "MetroCenter" turns out to be a shopping center that looks like every other shopping center in the country) and abandoned shopping centers that have turned into mega-churches. It's a fairly long ride to the airport, especially in Phoenix traffic, which is dreadful.
There's a small pool with what I guess was water in it -- but I wouldn't risk swimming there!
The staff was generally clueless -- one spent most of his time hitting a computer keyboard as hard as he could, complaining about the keys not working and had no idea how to get to the Frank Lloyd Wright house (though the advertisement for the hotel lists it as "nearby" -- it turns out it is on the other side of town). The rest of the desk staff seemed unaccustomed to dealing with people and looked confused when we asked them questions.
The hotel seems to book large groups (a university baseball team was checking out the same morning we were leaving) and, in general, the hotel gives the impression that its guests as potential troublemakers (perhaps a sensible guess if it is booking that many large groups!). So the rooms have lots of notices advising you not to steal things -- though I'm not sure what you'd want to steal -- and there is a staff member placed at the breakfast room to make sure you don't come back and eat two breakfasts -- though, again, given the rather dreary assortment of high-fat, high-sugar items available, I'm not sure who would try to sneak back.
There's got to be a better place to stay in Phoenix for the price.
