When we need to be in Sacramento a few times a year, I always check the price of Hyatt House first.
The rooms are very clean, there's a lounge/restaurant on premises, and over a dozen other places to eat or drink within a quarter-mile radius from the hotel.
The included breakfast, whereas still not up to European standards, is a step up from most American hotels (and certainly far above American motels).
Occasionally something is happening in town (sports game, political things, conferences, etc.) which might make the price of Hyatt House exorbitantly high, but as long as it's roughly between a hundred and ten to a hundred and eighty, they receive my business.
There are rooms that also have have equipped kitchenettes, which could be great if you need to stay for a long time.
Short-term metered parking in the area can typically be found, and they do have a valet parking service, but I don't know how much that costs. It's ideal to be here without a car, and as long as you can enjoy/walk in Sacramento's heat, or take advantage of Sacramento's light-rail system, you can get anywhere you would need or want to go.
The air conditioning systems in the rooms are excellent as well, and the bedding, and beds are very comfortable. It truly feels like a major step-up if you can get rates between a hundred to a hundred eighty. Above that, I'd look for air bed and breakfast places instead (and we have).
Oh, it is also about only a block from the Sutter Medical Center.
