Santorini - Imerovigli has amazing choice of hotels. 3 nights - 3 adults Budget 2000 - 2700
I choose Imerovigli for higher elevation so unobstructed sunset views.
I think all or most of the hotels offer includes breakfast.
Astra suites Looks good but looks heavily promoted
Santorini Small Luxury Hotels of the World - nice but little isolated, hence long walk or taxi
Santorini princess spa hotel
I am sure there are more in this price range with infinity pool, toilets with doors (as some don't have them).
Any recommendations?
