We have talked about staying at Rio many times. but always opted to stay on The Strip. I am glad we tried Rio this past trip (Jan.23- 25th, 2014). We really liked it. We are both highly sensitive by cigarette smoke and after reading other reviews I was afraid we would find the casino to be too smokey. That was not the case at all. Neither of us we bothered by the smoke.
Our room was very clean and spacious. We did get a Samba Suite room, recently renovated. The mattress was wonderful.
My only negative is with the bathroom. At 3:00 PM it took forever for the hot water to warm up and it never did get hot, just warm. Also, the showerhead seems to be a low-flow head and the pressure did not work well for getting my hair rinsed. Comparing this bathroom to some of the bathrooms in other LV resorts we have visited, this one is very small and not impressive.
We did enjoy the place though, found it to be easily navigated and friendly. We would stay there again.More
