I would highly recommend Vivi as a host - she not only had a wonderful place to stay at which was in the heart of Fira, but she also went out of her way to make the visit pleasant. She helped organise our airport transfers, she met with us and gave recommendations of things to see etc, and she was always available if we had any questions.
The house itself is lovely, with a comfortable bed, nice balcony that can see the ocean, and a nice big shower. The kitchenette is equipped with a microwave and 2 burners to cook, and the wifi is very reliable.
In all, we would not hesitate to stay with Vivi again, and I recommend you do too! Thanks for a lovely stay in Santorini Vivi.
