What a wonderful retreat! I was traveling alone and felt safe and secure in Soni's backyard. It felt very much like camping and I felt the same immediate relaxation and rejuvenation that I do when camping. Just like camping, there wasn't a lock (at least that I could find) on the trailer, but I felt safe and snug in their backyard. I was nervous about going into their house to use the toilet, but they were so warm and mellow, it wasn't a big deal. And as others have said, the shower is really awesome. Overall an amazing little retreat.
