When we first arrived, I was alarmed that there was no air conditioning. It was a pretty hot summer day for the area. However, we opened up windows, and it became more comfortable fairly quickly. I found out from talking to others, that this is pretty normal for the area.
Overall, the house is pretty awesome. I have stayed in a few VRBO properties, and this is one of the nicest! The house is stocked with games, movies, access to Netflix, kitchen and bathroom essentials, and overall clean and comfortable!
It is a beautiful location. The drive over the Teton Pass going into Jackson can be a little scary at first, but not near as bad as we expected.
