I cannot recommend Red Stone Villas highly enough. My wife and I stayed there for 9 nights and it exceeded all expectations.
It is located in the traditional village of Finikia which is a nice 10 min walk from the main area of Oia. It was a perfect location as it had the beautiful views of the sunset that people go to Oia for, but without the hundreds of tourists or crazy prices. The village has no cars so is very peaceful and is made up of traditional Cycladic churches and cave houses so you really are getting to see the real Santorini. There is also 2 of the best restaurants on the Island (Lefkes and Meze Meze) which are less than 5 minutes walk from the villa and were far nicer than any of the tavernas on the main strips that we tried.
Markus our host was brilliant! He arranged for a car to collect us from the airport which was cheaper than a taxi would have been. He was there to meet us on arrival to bring our bags to the villa and then gave us the full tour. Throughout our stay he was always available to make recommendations of places to visit & eat (definitely go to Galini for lunch) as well as he was able to book a quad bike for us so we could explore the island. Literally nothing was too much trouble for Markus and his partner Lorena and they would often surprise us by the pool with a glass of wine or croissant. They also offered daily room cleans with fresh bedding and towels, this was something I had not at all expected and was the icing on the cake.
I knew from the photos that the villa was going to be lovely but it exceeded all our expectations. It has only been open a month (hence the small number of reviews at the moment) so everything is brand new and every detail has been thought of. Our suite was made up of a kitchen area (fridge, freezer, sink, kettle, coffee machine, crockery and glasses) which was ideal for making breakfast and lunches (there is a supermarket about 5 mins away to stock up the fridge with treats) to enjoy by the pool, a stunning bathroom with a very powerful shower, a lounge area with a TV and 2 sofas and the bedroom with an extra large and super comfortable bed. There is also of course the all important wifi.
The pool area had loungers, umbrellas, towels and was a perfect place to relax and cool off after a day exploring the island.
If you are looking for an amazing place to stay, in a stunning location with a great host at a superb price then book now, you will not be disappointed!!
