Where to park car overnight near Club Quarters

Flying into Houston IAH from SFO. I’ll be in Houston next weekend from Saturday through Tuesday. Will be staying at club quarters. As I did my research I decided to rent a car since it sounds like Houston public transportation isn’t good and things are spread out.

where can I park my rental car, preferably near club quarters in downtown, over night for these four days? Will be using the car throughout The days I am there but worried about overnight parking.

The premier parking at @ 400 main lot seems like my best bet. Thought I would ask here to get better insight from locals. Any help is appreciated.
