If you are in Milos, you need to book this place. Giannis treats you like family. We were so grateful for his help during our stay. Giannis offered to pick us up and drive us to the house. He also helped us carry our luggage across the beach, and stocked the fridge with fresh eggs, olive oil, coffee, tea, waters, ouzo, and snacks. Giannis is the man. The quad we rented ended up being out of gas and broken, and Giannis came to the rescue. He brought us a full tank and made sure we would make it back to town. On our last night, he brought us a local bottle of wine. On the morning of checkout, Giannis made us a special parting gift, helped us walk our bags across the beach, and drove us to the port to catch the ferry. He even offered to print our tickets for us.
As for the cave house itself, it was magical. We had our own private beach in the evenings with incredible sunsets. We were provided snorkel gear and all of the linens, details, and decor of the house were perfect. Truly an amazing experience.
