The Clarendon has some nice perks, like free wi-fi (however it was not working for one day of our stay), a nice outdoor pool area with a hot tub that stays open until mid-night, and my personal fav: free candy/snacks/water available at the front desk around the clock.  I like those extra touches, and appreciate them, but unfortunately they miss the mark in other areas.  It looks like they've tried to update the rooms, but they have a ways to go.  There were several things that I thought were just plain odd- no overhead lights, and no switches that turned the lamps on and off- each of the lamps (there were 5 in my room) had to be turned on and off by a switch that was attached to the cord.  There's a cordless phone in the room, but there is no directory in the room with information about how to make calls, or even how to call the front desk, etc.  The alarm clock is old and doesn't work, in fact most the buttons were so worn that you couldn't even tell what you had to press to set an alarm.  Also, the bathroom is small, and I had a lot of difficulty getting hot water- all of my showers were lukewarm.  The dead bolt on my door did not work, and I had to get my room keys reactivated three times in one day.  Also, the hotel itself is in a weird location- there is virtually nothing within walking distance.  I will look at other options on my next trip to Phoenix.
