“My husband and I stumbled onto this fabulous Inn and what an unexpected find it was. Old and quaint and loaded with charm. We enjoyed a couples massage that was one of the best I've ever had and the mineral baths are PRIVATE. Quaint is code for "not everything is modern or perfect BUT this place is not to be missed if you are looking for laid back and romantic.“
