Nicely updated
We have stayed here several times before & are never dissapointed. It was our 37th anniversary when we checked in, I had booked a King - parlor room & asked for an upgrade when we arrived, telling the clerk it was our 37th anniversary - that day. She said she'd upgrade us to a King suite with a view of the atrium, but I REALLY wanted a balcony. It took some insistance on my part, she really didn't seem to want to give us what I wanted, but after talking to her manager in the back, she accomodated us. we were there for three nights (Thurs-Sun)
We were in room 1810, very close to the elevator (but never heard it from the room). It was a FANTASTIC suite. It had recently been updated. The decor was what I call "Texan".The floors were immitation hardwood - no carpet, a large granite wet bar, a table w/4 chairs, a living area w/flatscreen TV, floor to ceiling windows w/ a sliding door out to the balcony, and a half bath (with immitaion cowhide walls). The King bedroom was a bit cramped, but beautiful, also having the same window set up as the living area with access to the balcony & another large flatscreen TV. 
The bathroom was to die for! It was huge with an all glass, oversized shower & granite countertops. Super, super nice. 
The noise from Sixth St is LOUD at night.... until the weeeee morning hours.... but when you close the balcony doors, that noise is almost totally gone. So that was good. They offer earplugs in the room with an explanation that the noise can be disturbing to ones sleep. It didn't bother us. 
The pool is on the rooftop & very HARD to get to. You take the elevator to the 20th floor, walk down the long hall to a door, then walk up an un-airconditioned stairway (triple digit heat makes that HOTTT) to the pool deck. There was an older lady struggleing to get up the stairs once when we went up there. I felt bad for her. There are no restrooms on the pool deck, you have to go back into that HOT stairwell, down the hall to a "single" bathroom. There is a locker room just off the stairwell door, which I finally decided to check out.... finding there were restrooms (both men & womens) in there. The pool is stainless steel, long & narrow. The water made your skin feel sticky. I didn't like that. But the water temp was good & the strong winds (remember you're on the 21st floor) kept you cool! They have a rooftop bar, but their margaritas left a LOT to be desired. We told the bartender & tried to make better ones, but we gave up. The pool has glass walls looking out over the city & the view is awesome! 
They didn't even wish us a happy anniversary. Which kinda bothered me. My husband asked the hotel concierge to help him get me flowers delivered to our room for our anniversary & they couldn't. REALLY? The staff seems distant & just there to do a job. Very unlike the Omni La Mansion del Rio in San Antonio which bends over backward & is happy to make your stay a wonderful experience. (We had stayed there two nights prior to coming here). But this is a BUSY hotel (sold out on the Sat night we were there - our friends tried to book a room so we could hang out more together) :-( 
We valet parked our car (which is new). When we got home & washed it the next day, I found a pretty nasty scratch on my lower bumper which was not done by us. We are SUPER careful. I assume they were driving it up (we came & went alot over three days) the ramp from the garage & clipped the wall. I didn't even call about it, as I have no way to prove any of their drivers did it. Just hate that my new car has a bad scratch. :-(
