We loved our time in Santorini.
Imerovigli is a great location to stay as it is in between Thera and Oia.
Themis helped us make reservations (highly recommend the morning catamaran trip) and was very communicative.
The room was very clean and breakfast in the morning was lovely.
The only small “complaint” I would have is that the views aren’t what we expected, opposite side of the Caldara. Overall though our stay was great and the service and room wonderful.
