Clara was a great host -- very responsive, friendly, easy to get in touch with. The house is clean, spacious, and at an elevation -- so the temperature was pleasantly cool considering Rio's summer heat. The Wifi signal was good, around 60mbps speed.
The reason why I stayed for 1 night instead of 12 was that the house was right next to a highway and the bedroom window didn't have glass to block out traffic noise-- only solid wooden shutters. Since I was planning to work from home the noise was an issue for me. But if you're coming to spend most of the day checking out Rio this might not be an issue, as the noise calms down at night.
It's also worth noting that there are 2 big dogs (very friendly) that are kept in the outside area, and a cat that lives in the house. I love animals but would have appreciated a heads up, I also have a cat allergy.
