This place was astonishing. Prepare to get to a grocery store, there are a few nearby that are really convenient and have great food, so that you can cook or just assemble some snacks and make sure you are in the place for sunset every day.
Do not plan an itinerary that has you not in this location for sunset every day.
We spent maybe three evenings out, staying for 9 days. (And yes you can stay for 9 days and remain entertained - you do not need to live on a ferry. Santorini is a very diverse island.)
The pastry and general store, The Family, that's open 24 hours is also a really great feature. It's a five minute walk.
The amenities are also lovely - great shower, stove (again, we did actually cook there! all functional), coffee things. The space is breezy but the tables and wifi are effective if you have to set up to do remote work. (Alas, but I did.)
