LOCATION - This cache is hidden on a little wooded hill between a main road and a quiet paved road. given there is no one at the coordinates, you shouldnt have any issues with muggles as the foliage provides sufficient cover. With that said, a little stealth never hurt anybudy.
SIZE - Its about the size of a stick of deoderant. there is a physical log and room for some knicknacks.
Finally as for all geocaches, make sure to put it back the way it was with care. Enjoy.
