We had a great time renting from Shelly! The 4Runner was in great condition and allowed us to see so much of the island and made this booking an excellent value. We were able to cook our own meals for a few days using the stove and cooking utensils provided, which saved us a lot of money as Kauai is definitely expensive.
The only thing I would add is that I'm not sure I would recommend this Airbnb experience for four people. The tent provided is very small and is not waterproof (we figured this out at 4am when we woke up to a flooded tent). It rains A LOT in Hawaii so even though we wanted to sleep in the tent, we were forced to sleep in the car. If we had been traveling with four people, I'm not sure what we would have done as the car only sleeps two. The tent mattress was also not large enough for two people to sleep comfortably. It's closer to a twin size than a double size. We were also only given one headlamp and one set on bedding, which was inconvenient when the tent flooded and everything was soaked.
Overall, this was a great find and I would definitely rent from Shelly again so long as we're just traveling with two people :)
