We had a fantastic time at the Armeni Beach House! Nicoletta went above and beyond in welcoming us early in the morning due to a last minute change in our flights. She even arranged the early transfer to Ammoudi and boat ride to the Beach House. There is quite a hike up the hill either from Armeni or Ammoudi Bay but if you rent a car you can park almost all the way down into Ammoudi Bay and Alexander is almost always available for the boat ride to and from the Beach House.
Our kids are teens and spent most of their time on Santorini hanging out at the Beach House, swimming and kayaking to the rocks for diving.
We highly recommend the Beach House for a relaxing vacation and jumping off point for exploring the rest of the island. I do recommend renting a car.
Thanks so much for the great vacation!
