We stayed for three nights, two adults and two children. The house is comfortable and stylish, really captures the vibe of Oia. The location is excellent with fantastic views, close to the main walking path, but far enough away to have some privacy. The folks just above the house run the bakery across the main path - excellent baked goods, very reasonable prices.
Maria is a great host, responsive and helpful. On one occasion we requested some beach towels, and on another the hot water had gone out. Both times, Maria responded immediately and we were good to go within 20 minutes. We had a fantastic stay and would love to come back!
