Looking at other reviews, it looks like the rooms may differ so I can only comment on the room that we had: #530. We are fussy travelers & rarely travel because of it. We were at the Hyatt for DesignCon . Room: Walls looked like someone threw up after drinking champagne,really not attractive. Beds: There were 2 beds in our room. They were on the firm side. My husband said he felt sore the next day, though I was fine. One bed had sheets so "crisp" that they crinkled like paper...all...night...long. The other bed had softer sheets. The beds were made up with a bottom sheet (not fitted) and a paper thin down comforter in between 2 sheets. I did not like this arrangement as the top combo only came up to the top of my rib cage. Everything was tightly secured though once you untucked the sides & the folded over stop sheets, it was just a mess. Lighting: The room had plenty of lights, but needed more light, like an overhead bright light. Drapes: our room faced the rising sun & the drapes were heavy, superior light blockers. I was very impressed. Heat/Air : the heating /cooling unit was on a wall next to the windows & did not face the room. This meant that if you were in bed, you weren't getting air blown on you directly, which was a very good design. Also it did not seem overly loud, though we did not have it on during the night.Refrigerator: was in a cupboard next to the desk & drawers. Worked fine (had no freezer area). This was one of the quietest fridges I've ever experienced. We were 1 room from the ice machine & 1 room from the housekeeping closet. Never heard either which surprised me.(but then I slept with earplugs & noisemaker <though that rarely will help completely with sound...yeah, I'm that sensitive to sound!) Corridor room doors were loud when they closed. We did not hear any walking above us. We did hear the airplanes from San Jose Airport & the train horns from wherever they were. Bathroom: had motion sensor nightlights...nice but the doors were frosted glass & the lights didn't turn off for a long while afterwards..so not so good for sleeping. Bathroom had NO fan, This is a big negative as the mirrors fogged up & you kinda want a fan for odors. Lighted magnifying mirror in bathroom was big but magnification was not enough (for a woman)husband found it adequate to shave. Bathroom floor was tile (?) when you put down the bath mat ( a towel basically) it was dangerous because it slid all over. Husband hated the square shallow sink. I did not like it as the drain had a slotted dome over it that stuck up a good 2-3 inches, so washing hair in the sink was kinda impossible. Bathroom doors were AWFUL ! 2 wood doors (with frosted glass in the middle) on casters that were SO loud to move and banged shut when they met. Ridiculous design. Toilet was one of the quietest I had ever encountered in a hotel, which is a joke as the doors were so loud.Closet was adequate size but open to room. 1 cotton blanket in closet & 1 extra pillow. None of the pillows was foam or firm. Dresser drawers were pretty quiet to open & close. Room card has to be used when you got into elevator in order to select a floor. It didn't work very well & was very annoying to use. It also took a few tries to get it to open the room door. There were Lots of outlets & plenty of USB ports in the room Parking: parking garage is NOT attached to the hotel & there is no convenient or easy way to drive up & drop things off when you register. The back of the hotel is not easily (quickly) accessible to the parking area. This, being California, the weather is good alot, & the sidewalk from the garage to the side hotel entrance did have a canopy top.Parking did not cost. I did not find the concierge people to be knowledgeable or helpful, they seemed pretty clueless.
