I do think Pyrgos is a hidden gem in Santorini and is a must good village other than Fira and Oia. If you decide to stay in Pyrgos, Nikos' house is a good choice.
The house has a fantastic view over Fira and landscape nearby. Nikos is a attention to details and presented us a welcoming gift and prepared a local wine for our enjoying. Also, thanks for his mother pick up.at the airport and detailed introduction on the house.
The house is clean and tidy and it is suitable for staying for at least a few days.
Highly recommend if you decide to stay in Pyrgos!!
