Essentially, the Rio is the locally branded version of a Motel 6. It's cheap. The rooms are large (lots of empty 80's carpet). If you are looking to save money and sleep with 10 of your best friends from college on the floor, it's a great deal.
The place is run down: The shower is moldy. The surfaces are either dirty or permanently discolored/roughed up. There are many light bulbs burned out all over the place. Where the elevator button was is now a hole punched in by someone.
They charge you to check in before 4 PM.
On the plus side, the gym is included. The gym is part of the spa. You won't find it on the map. Because it's part of the spa, you get the sauna and hot pool for free as well. The gym is bare bones. There are some treadmills and weights.
Tip: There is a rad Japanese AYCE restaurant near the hotel in a strip mall: Umiya (4.5 stars on yelp).
