Beautiful location
"What a great stay! This tiny home had everything we needed and more right down to the sunscreen. We stayed for three nights. It was clean, quiet and just what we needed for a relaxing stay. Just make sure to bring the bug spray - the mosquitos are pretty busy around the campfire."
