Directions to Casamediterranea:
Reached the second input of Sperlonga (from the direction of Rome, or the first direction and from Naples), turn right and follow Provincial Road 105 to Itri.
After about 4.5 km. turn right (the sign Casamediterranea) proceed with caution because this is a old mule.
Follow for 300 yards and then turn right (you will find more signs).
