Some of the most wonderful people that we’ve ever dealt with on AirBnB. They were very responsive when we had questions, and gave very clear instructions regarding how to proceed with accessing the van.
As for the experience, this is by far the most amazing way to enjoy the island at your own pace, and gives you the freedom to be as adventurous (or not) as you like. You won’t find a better deal, or people to deal with than this!!
