There are different types of value. Qualitative and quantitative. This apartment is definitely of qualitative value. What I mean by this is the view on the terrace is just spectacular, really priceless in value. I completely enjoyed sitting on the terrace in the morning and evenings. However, the other kind of value is the cost of staying on Santorini. It is an expensive island to stay on. The restaurants are somewhat expensive, items at shops are outrageously priced, and finding quality food to cook is not easy. All in all it is a fantastic, historical place to visit, but four days is plenty.
