I highly recommend Anna Pension for a stay in Santorini.
The place is perfect for enjoying the island and not that far from cities by car. You will find there a beautiful place with a nice swimming pool and all you need in the room. The room is of all comfort, modern and above all extremely clean. We never find a room that clean as the one Andreas proposed us in all our stay in Greece. Also, everything is more than well done in common parts for health security. If you want to spend a journey in Santorini with serenity even in that particular period, I recommend you going there.
Cannot wait to come back. Best wishes !
