Everything about Mare Nostrum Santo was perfect - very clean apartments, excellent communication always, personalised service, beautiful views from the apartment. Two minute walk to the beach, 5 minute drive to the most beautiful town on the island; Ia/Oia. The hosts were so so helpful in every way - they helped us book a private transfer from the airport at 3 am on our arrival, they always asked us how we are doing, if we were enjoying our stay and our trip, as well as gave recommendations for things to see and do. I highly recommend booking an ATV or scooter in Santorini. It's the best way to get around the island - beautiful views with wind blowing in your hair. The hosts helped us order an ATV to be delivered to the hotel within one hour at the best price we could find on the island. Finally, rather than booking a taxi to go to the bus station, they offered to personally take us to Oia. Truly amazing hosts! I will absolutely come back when I'm next in Santorini. Can't recommend them enough!!
