Nikos was a great host and very helpful meeting up with us and telling us about all the best locations to visit on Santorini. The house location in the heart of Mesaria is a perfect central residential area on the island to get away from all the August crowds and noise of Fira or Oaia if you have any transportation. Just be aware that if you rent a car you will usually park it a couple of hundred meters from the house itself. This was never an issue as parking was readily available on the road from the center Mesaria intersection leading to the 200m of residential alley roads up to the house. There are 2 good supermarkets, a bakery and 5+ restaurants and cafes in the center Mesaria intersection near the orange sign Proton Supermarket where Nikos requested to initially meet on our drive from the airport (easy to find straight shot intersection from JTR). Nikos recommended Kamari beach which was excellent choice with a beautiful laid back boardwalk (relative to more upscale Fira and Oaia areas) with numerous restaurants right on the edge of the beach with rental umbrellas and lounge chairs available and easy close parking even with the peak August crowds. The Nefeli Caves AirBnB unit was the upstairs cave unit of 5 conjoined rental units and Nikos had them all rented out so he was staying next door with his neighbor Delfina so was always readily available on the adjacent deck for any questions we had which was very convenient and helpful. The inside cave house itself is very nice with modern bathroom, kitchen, and high ceilings so plenty comfortable and cools down pretty quickly with A/C. The WiFi signal doesn't reach well into the unit itself , especially if door is closed for A/C, so expect to use out on the shared deck area if you need access. Our visit overall at Nikos place was great and we would certainly stay there again if visiting Santorini during high season.
