We loved our stay at Elenis Cave House a lot. Its a great place to stay in beautiful Pyrgos. To Fira, the easiest way to go is by Bus. For the other attractions of Santorini, the best way to visit is by renting a car (car rental in Pyrgos at the main street). The accomodation is amazing, very clean and comfy. You enjoy a small rooftop terrace. Eleni is a great host!
