Great experience at Mare Nostrum Santo! Penny was a great host being very responsive from the moment I made the reservation. She arranged a taxi that picked up us from the port which worked out perfectly and then she called a rental car company that delivered a car for us to the villa with no charge. The place is located near Oia, perfect spot to discover the island. If you are on a budget I recommend buying take away food in Oia and take it to the villa to eat there, so quiet and relaxing. Also The breakfast was great! A lot of food and everything was delicius, specially the omelette and the yogurt.
