My husband and I were on our honeymoon and we LOVED our stay at Elias's place. The price was amazing for the location, the sea view, the pool, and how helpful Elias was. Elias's place was also extremely clean, which we appreciated. The villas are about a 5 minute walk from Firostefani, which was our favorite part of the island. Inside of the villas themselves is lovely-the pool is beautiful and there are all these gorgeous flowering plants. There are also common areas for everyone-a balcony, a few pool chairs, and some tables to eat at.
We recommend staying here for the majority of your trip (3-4 nights) and then staying in Oia for one or two nights with a view of the caldera. Best of both worlds. :)
