Excellent family holiday, together with our 6 year old son, we spent a week in Santorini with our base at Caldera Romantica.
It is a good honest 3-4 star hotel, friendly and excellent staff, clean rooms, very comfortable bed. Breakfast was included, and was a good buffet.
The location is near Akrotiri on the south end of Santorini, offering beautiful views of the volcano, and Fira and Oia nestling at the edge of the caldera in the distance. It is very quiet, away from most of the tourists in Fira and Oia, which we liked very much. Fira is 10-15 minutes drive, our favourite beach at Perivolos is a similar distance.
