This is the best no-frills motel close to UC Riverside with all of the conveniences you'll need. Dynasty Suites has a wonderful staff that goes above and beyond when it comes to customer service - allowing me check in at 7:30am on the day of my reservation for a small fee, so I could get online for work meetings.
WiFi is really, really good - I had zero problems with two full days of back to back Teams/Zoom meetings where I was presenting, sharing slides, etc.
Dynasty Suites is a 5 minute drive to my son's dorm on the UCR campus and is surrounded by restaurants, convenience stores, gas stations, etc.
I had a room with a king-sized bed and couch, which was a pull-out, so plenty of space and it's comfortable. The AC/heater worked very well and there's a ceiling fan for extra cooling if you need it. They had a larger sized refrigerator in the room, a microwave and hair dryer. They also have more toiletries than most - toothpaste, mouthwash, razor, shaving cream, etc.
A unique touch is finding murals on the ceiling at the front desk and within the rooms.
