Extremely overrated for a old hotel and some unqualified staff
I've just returned from a conference in Phoenix and I must say that the so great location people talk about is the same for almost all downtown hotels in Phoenix. There are probably more than 4 or 5 hotels which are very close to the convention center so don't fall for that.
I was very disappointed with this hotel because for a reasonably expensive hotel it has shown some serious flaws which make me want to never go back there.
First of all, I understand that some hotels charge for packages handling, but some hotels don't! I would have appreciated if this hotel did warned me when I made my first contact informing that I had some packages to be delivered at the hotel. They only said that it would be a honor to receive then nothing more. I've stayed in a Hyatt hotel in Salt Lake City before and there was no charge for that, how was I supposed to know that in Phoenix they would charge me if they didn't warn me? So I think that for the price of the room, it's a very greedy attitude and even if they insist to charge, they should let the guest know about that, specially when they contact the hotel to inform about their packages.
Second, they also charge for the internet, which in my opinion is also wrong. It should be included in the price since almost everybody is there for business (there is nothing else to do in the city!). Anyway, they charge for internet but they give it for free if you join their gold-passport-whatever-group which can be made at check-in. But "surprisingly" they don't inform all the guests about this complimentary service...
Third, the room is ok but there is no safe, they have a very small bathroom, very stained bath curtains, terrible hair dryer (I had to buy a new one at CVS) and housekeeping kept forgetting to give us soap! Awful!
Fourth, the service at the rooftop restaurant was very poor... We arrived at the restaurant by 10pm and we had no idea they had already stopped serving food, anyway since there was anyone at the reception we took a seat. A very rude lady took us out of the seat and then back to the same place we were! She waited for us to order drinks and just let us know that there was no food afterwards... It was very unpleasant! We ended at the Networks Bar which is quite nice. 
Fifth, it is probably not the hotel's fault but the rent-a-car service installed at the hotel offered a terrible service! First a guy named Kevin, from Enterprise rent-a-car told us that they didn't have a car to rent then we called the company central service to get a car from another location and for our surprise they told us that there was a car available in the hotel! We went back to that Kevin guy and for HIS surprise we had a reservation for a car! He said that we could have the car now and that he was doing us a favor because the car wasn't supposed to be rented. It really wasn't, because it was all dirty and I bet that Kevin didn't do his job right because he was supposed to have that car cleaned for renting! So Kevin was not doing us a favor... on the contrary, he wasn't doing his job right. I blame the hotel for allowing such person to provide services under their consent.
Despite all their flaws, I have to say that I experimented a very competent service at check-out by the proper manager and also very good service from the guys in the front door that arrange taxis, etc. They were very polite and helped me a lot.
