We LOVED staying at this villa. The location is seriously to die for. Its really not an exaggeration that the view from the villa is the postcard view of Oia. Amazing! The cavehouse is like nothing we've stayed in before, so that was fun! There were 8 of us (4 adults, 4 kids), so it got a little crowded at times, but we really didnt spend that much time inside anyhow. Given that we had kids, a larger tub would have been more fun, but we still used the tub everyday and it was fun. Because of the incredible location and backdrop, there are definitely tourists who try to get pics there, so its not 100% private. It didnt bother us much but it might for others who want super privacy. Also, there's an older woman who lives in the villa above who is always yelling at trespassing tourists - she's awesome, we ended up befriending her :)
But by far what made this place extra special is Nick's hospitality. He was there to meet us in person, and shared the background of the place with us; his crew (thank you Petros and Armando!) are extremely equally helpful. From carrying our luggage up and down the many stairs in Oia, to accommodating our questions, to booking us breakfasts and dinners and sailing trips, they have really gone above and beyond. Nick also connected us to an awesome person (George), who took us all around the island - including all the way up to the Monastery (not for the faint hearted!). When my dad lost his passport, George spent many hours re-tracing all the places we'd been in until he located the passport. I feel we've made friends for life on this island and we will definitely be back. Thank you!
