We had a great stay at Ersi Villas. Elias is a very welcoming host and his tips for the island were all excellent. (The walk from Firostefani to Oia really is the best thing to do on Santorini - highly recommended!) The room was clean and the atmosphere at Ersi Villas is very friendly too. Elias also helpfully picked us up from Fira bus station and took us back there when we left. All in all, we are very happy we stayed here!
