There is not one suggestion for improvement that I would make. Jim and Elaine were completely flexible regarding times to check in and check out, left us waters and snacks in the kitchen, and provided quick responses to any questions we had. In fact, when the handle on the BBQ tank welded shut from the heat, Jim ran over to the house and provided a new tank for us to use within five minutes time.
The place was nice and clean, very spacious, and the beds were comfortable. Also, the jacuzzi was a terrific amenity.
Overall, excellent hosts and an excellent experience. I would give more than 5 stars if I was able, and will certainly be on the lookout for this place next time I travel to Vegas.
