Vailiki was very helpul and let us check in really earlier than expected.
She showed us all around the area.

The apartment was very clean (also cleaned every day during our staying) and organizing.
It's perfect for 3 people.
It's very well situated in Kamari : 2 minutes walking to the beach, 2 minutes from a free parking, just downhill to the Ancient Thira (archelogical site).
It's very well situated in the island too: very central, 20 minutes from Fira by car, 20-30 minutes from Perissa, etc.

The swimming pool is great because it's high so you have sun very late and you have an amazing view over the mountain and the sea.

I strongly recommend this place to stay in Santorini.
We had an outstanding time there.
