If you want to visit Oia without the crazy crowds, White Grape Suites is the perfect choice. It is in a small village just a 10 minute walk down the road from all of the shops and sights. Finikia is quiet and beautiful. The team (Eleni and Sotiris specifically) were incredibly welcoming and helped show us around and set us up with a sunset boat tour. The room itself is a charming and cozy cave from the 1800s. I would 100% recommend this spot to anyone traveling to Santorini.
