There is a great view from the cave home and it was quiet and a little bit removed from the main flow of wlaking traffic which was nice. You can walk to all the shops and restaurants in Oia, and also to prime sunset watching locations. Maria was super friendly and very helpful, even setting up a porter and taxis for us. She talked us through all the things we could do, marking a map she brought for us to use as she did.
P.S. Pito Gyros is a must stop. Great food and value.
