Amazing value in Imerovigli in the heart of things. The building faces the eastern, non-caldera side of the island but still has beautiful, unobstructed views of the sea. Its less than 50m from the caldera walk with all the spectacular cliffside restaurants for a fraction of the price. Walking distance to Fira, the main city with more shopping and restaurants.
There is a moped/ATV rental place located next door that is very worth it considering how expensive taxis are and how infrequently the bus comes. 40€ per 24h for an ATV.
Yannis, the property manager, was excellent and had great recommendations on what to do on Santorini with his honest opinion on what was worth it vs. overpriced. He was responsive and offered to let us switch rooms when there was a noise issue coming from the building next door. The free breakfast was very filling and great. The only small suggestion I have for improvement is add some variety, since the breakfast was the same every day (omelets, bread, jam, and deli meats). But that is very minor.
Overall an excellent stay and great value.
