We were blown away by the great service provided by Maria. She responded quickly to all of our questions, including once we arrived. She arranged to have a taxi meet us at the airport, and once we arrived at night in Santorini, someone was waiting at the taxi stop to help us with our luggage and lead us on the circuitous cobblestone path to our cave dwelling. Once there, he told us how everything worked and asked us if we needed anything. Every wall of our dwelling was curved and hand-plastered. It had a 'Hobbit Hut' feel to it -- we loved it. Best of all was the view from our patio to the sparkling Aegean Sea. The cave dwelling is in the heart of the old town of Santorini, not far from the blue-domed church.
At the end of our stay, the man (Vaseli?) met us and once again helped us up the meandering path to our taxi.
We highly recommend Maria's lovely rental.
