I stayed there last month (20 nights) on my business trip. $10 for self park each day, they were doing some construction at the hotel front entrance.
First five nights were upgraded to the corner mini suite, it was an ok room tiny bit bigger than a regular room, really old carpet, old bathroom. The breakfast at the club lounge was ok, no more evening snack etc@evening, only in the morning.
The last week of my stay, they upgraded me to the executive suite on the top floor, bigger room with wet bar dining room living room 1 1/2 bath, much nicer but still old and the carpet smell.
Try Westin Galleria, the rate are higher but better and free self park too.
